The ADL8121 is a gallium arsenide (GaAs), monolithic microwave integrated circuit (MMIC), pseudomorphic high electron mobility transistor (pHEMT), low noise wideband amplifier that operates from 0.025 GHz to 12 GHz.The ADL8121 provides a typical gain of 16.5 dB, a 2.5 dB typical noise figure, and a typical output third-order intercept (OIP3) of 36 dBm across the 0.025 GHz to 10 GHz frequency range, requiring only 95 mA from a 5 V supply voltage. The saturated output power (PSAT) of 21.5 dBm typical across the 0.025 GHz to 10 GHz frequency range enables the low noise amplifier (LNA) to function as a local oscillator (LO) driver for many of Analog Devices, Inc., balanced, in-phase and quadrature (I/Q) or image rejection mixers.The ADL8121 also features inputs and outputs that are internally matched to 50 ?, making the device ideal for surface-mounted technology (SMT)-based and is housed in a RoHS-compliant, 2 mm ? 2 mm, 6-lead LFCSP.APPLICATIONSTest instrumentationMilitary communicationsMilitary radarTelecommunications

The AD8337 is a low noise, single-ended, linear-in-dB, general-purpose variable gain amplifier (VGA) usable at frequencies from dc to 100 MHz; the ?3 dB bandwidth is 280 MHz. Excellent bandwidth uniformity across the entire gain range and low output-referred noise makes the AD8337 ideal for gain trim applications and for driving high speed analog-to-digital converters (ADCs).Excellent dc characteristics combined with high speed make the AD8337 particularly suited for industrial ultrasound, PET scanners, and video applications. Dual-supply operation enables gain control of negative-going pulses such as generated by photodiodes or photomultiplier tubes.The AD8337 uses the popular and versatile X-AMP? architecture, exclusively from Analog Devices, Inc., with a gain range of 24 dB. The gain control interface provides precise linear-in-dB scaling of 19.7 dB/V, referenced to VCOM.The AD8337 includes an uncommitted operational current-feedback preamplifier (PrA) that operates in inverting or noninverting configurations. Using external resistors, the device can be configured for gains of 6 dB or greater. The AD8337 is characterized by a noninverting PrA gain of 2? using two external 100 ? resistors.

The AD8318 is a demodulating logarithmic amplifier, capable of accurately converting an RF input signal to a corresponding decibel-scaled output voltage. It employs the progressive compression technique over a cascaded amplifier chain, each stage of which is equipped with a detector cell. The device is used in measurement or controller mode. The AD8318 maintains accurate log conformance for signals of 1 MHz to 6 GHz and provides useful operation to 8 GHz. The input range is typically 60 dB (re: 50 ?) with error less than ?1 dB. The AD8318 has a 10 ns response time that enables RF burst detection to beyond 45 MHz. The device provides unprecedented logarithmic intercept stability vs. ambient temperature conditions. A 2 mV/?C slope temperature sensor output is also provided for additional system monitoring. A single supply of 5 V is required. Current consumption is typically 68 mA. Power consumption decreases to <1.5 mW when the device is disabled.?The AD8318 can be configured to provide a control voltage to a VGA, such as a power amplifier or a measurement output, from Pin VOUT. Because the output can be used for controller applications, wideband noise is minimal.In this mode, the setpoint control voltage is applied to VSET. The feedback loop through an RF amplifier is closed via VOUT, the output of which regulates the amplifier output to a magnitude corresponding to VSET. The AD8318 provides 0 V to 4.9 V output capability at the VOUT pin, suitable for controller applications. As a measurement device, Pin VOUT is externally connected to VSET to produce an output voltage, VOUT, which is a decreasing linear-in-dB function of the RF input signal amplitude.The logarithmic slope is nominally ?25 mV/dB but can be adjusted by scaling the feedback voltage from VOUT to the VSET interface. The intercept is 20 dBm (re: 50 ?, CW input) using the INHI input. These parameters are very stable against supply and temperature variations.The AD8318 is fabricated on a SiGe bipolar IC process and is available in a 4 mm ? 4 mm, 16-lead LFCSP for the operating temperature range of ?40?C to +85?C.Applications RF transmitter PA setpoint control and level monitoring RSSI measurement in base stations, WLAN, WiMAX, and radars

The AD8338 is a variable gain amplifier (VGA) for applicationsthat require a fully differential signal path, low power, low noise,and a well-defined gain over frequency. Although the inputs aredifferential, the device can also be driven with a single-endedsource if required.The basic gain function is linear-in-dB and is controlled by thevoltage applied to Pin GAIN. The nominal gain range spansfrom 0 dB to 80 dB for control voltages between 0.1 V to 1.1 Vwith a slope of 12.5 mV/dB. The nominal gain range can beshifted up or down via direct access to Pin INPD and Pin INMD,the current inputs of the VGA. For example, driving the INPDand INMD pins with 50 ? resistors shifts the gain range up by20 dB, that is, 20 dB to 100 dB, and lowers the input referrednoise of the device to 1.5 nV/?Hz. Additionally, the gain slopecan be inverted via logic Pin MODE.The AD8338 includes additional circuit blocks to enable inputoffset correction and automatic gain control (AGC). DC offsetvoltages are removed by the offset correction circuit, whichbehaves like a high-pass filter whose corner is set with an externalcapacitor. The AGC function varies the gain of the AD8338 tomaintain a constant rms output voltage. An externally appliedvoltage to Pin VAGC with respect to the voltage at Pin VREFsets the output rms amplitude. A capacitor from Pin DETO toground sets the response time of the AGC circuit.The AD8338 offers additional versatility by providing access tothe internal summing nodes of the VGA core and the outputamplifiers. With the addition of a few external passive components,users can customize the gain, bandwidth, input impedance, andnoise profile of the device to fit their application.The AD8338 uses a single-supply voltage of 3.0 V to 5.0 V andis very power efficient, consuming as little as 3 mA quiescentcurrent at mid gain. The AD8338 is available in a 3 mm ? 3 mm,RoHS-compliant, 16-lead LFCSP and is specified over theindustrial temperature range of ?40?C to +85?C.APPLICATIONS Front end for inductive telemetry systems Ultrasonic signal receivers Signal compression for driving an ADC AGC amplifiers

The ADMV4530 is a highly integrated upconverter with an in-phase/quadrature (I/Q) mixer that is ideally suited for next generation Ka band satellite communications.An integrated low phase noise, fractional-N phase-locked loop (PLL) with a voltage controlled oscillator (VCO) and internal 2? multiplier generate the necessary on-chip local oscillator (LO) signal for the I/Q mixer, eliminating the need for external frequency synthesis. The VCO uses an internal autocalibration routine that allows the PLL to select the necessary settings and locks in approximately 100 ?s.The single-ended reference input to the PLL operates up to 500 MHz and features internal reference dividers and a multiplier for added flexibility. Additionally, the phase frequency detector (PFD) comparison frequency can be up to 250 MHz for integer mode and 160 MHz for fraction-N mode.The upconverter consists of an I/Q mixer that can operate in either I/Q mode with 500 MHz of bandwidth or in IF mode up to 3 GHz of bandwidth, which allows various radio architectures and backward compatibility with legacy systems.Immediately following the I/Q mixer are stages of gain and variable attenuation. The configuration can achieve a minimum 1 dB compression point (P1dB) compression point of 19 dBm, eliminating the need for external stages of gain.A programmable 4-wire serial port interface (SPI) allows adjustment of the quadrature phase for optimum sideband suppression. In addition, the SPI allows nulling of LO feedthrough in IF mode. In I/Q mode, the LO feedthrough can be nulled by applying external dc offset to the differential baseband I/Q inputs.An IF automatic gain control (AGC) adjusts the IF variable gain amplifier (VGA) to compensate for input power variations. During normal operation, this AGC feature can be enabled or disabled via the SPI. When disabled during normal operation, the AGC feature only works on a test tone during power-down mode to track temperature variations.The ADMV4530 upconverter comes in a RoHs compliant, 6 mm ? 6 mm, 40-terminal land grid array (LGA) package. The ADMV4530 operates over the ?40?C to +85?C case temperature range.Applications Satellite communication Point to point microwave communication
