The HMC966LP4E is a compact GaAs MMIC I/Q downconverter in a leadless RoHS compliant SM T package. This device provides a small signal conversion gain of 12 dB with a noise figure of 2.5 dB and 40 dBc of image rejection across the frequency band. The HMC966LP4E utilizes an LNA followed by an image reject mixer which is driven by an active x2 multiplier. The image reject mixer eliminates the need for a filter following the LNA, and removes thermal noise at the image frequency. I and Q mixer outputs are provided and an external 90? hybrid is needed to select the required sideband. The HMC966LP4E is a much smaller alternative to hybrid style image reject mixer downconverter assemblies, and is compatible with surface mount manufacturing techniques.Applications Point-to-Point &?Point-to-Multi-Point Radio Military Radar, EW & ELINT Satellite Communications

The AD8319 is a demodulating logarithmic amplifier, capable of accurately converting an RF input signal to a corresponding decibel-scaled output. It employs the progressive compression technique over a cascaded amplifier chain, each stage of which is equipped with a detector cell. The device can be used in either measurement or controller modes. The AD8319 maintains accurate log conformance for signals of 1 MHz to 8 GHz and provides useful operation to 10 GHz. The input dynamic range is typically 40 dB (re: 50 ?) with error less than ?1 dB. The AD8319 has 8 ns/10 ns response time (fall time/rise time) that enables RF burst detection to a pulse rate of beyond 50 MHz. The device provides unprecedented logarithmic intercept stability vs. ambient temperature conditions. A supply of 3.0 V to 5.5 V is required to power the device. Current consumption is typically 22 mA, and it decreases to 200 ?A when the device is disabled.?The AD8319 can be configured to provide a control voltage to a power amplifier or a measurement output from the VOUT pin. Because the output can be used for controller applications, special attention was paid to minimize wideband noise. In this mode, the setpoint control voltage is applied to the VSET pin.The feedback loop through an RF amplifier is closed via VOUT, the output of which regulates the amplifier?s output to a magnitude corresponding to VSET. The AD8319 provides 0 V to (VPOS ? 0.1 V) output capability at the VOUT pin, suitable for controller applications. As a measurement device, VOUT is externally connected to VSET to produce an output voltage, VOUT, that is a decreasing linear-in-dB function of the RF input signal amplitude.The logarithmic slope is ?22 mV/dB, determined by the VSET interface. The intercept is 15 dBm (re: 50 ?, CW input) using the INHI input. These parameters are very stable against supply and temperature variations.The AD8319 is fabricated on a SiGe bipolar IC process and is available in a 2 mm ? 3 mm, 8-lead LFCSP_VD for an operating temperature range of ?40?C to +85?C.ApplicationsRF transmitter PA setpoint controls and level monitoring Power monitoring in radiolink transmitters RSSI measurement in base stations, WLANs, WiMAX, and radars

The AD8333 is a dual-phase shifter and I/Q demodulator that enables coherent summing and phase alignment of multiple analog data channels. It is the first solid-state device suitable forbeamformer circuits, such as those used in high performance medical ultrasound equipment featuring CW Doppler. The RF inputs interface directly with the outputs of the dual-channel, low noise preamplifiers included in the?AD8332.A divide-by-4 circuit generates the internal 0? and 90? phases of the local oscillator (LO) that drive the mixers of a pair of matched I/Q demodulators.The AD8333 can be applied as a major element in analog beamformer circuits in medical ultrasound equipment.The AD8333 features an asynchronous reset pin. When used in arrays, the reset pin sets all the LO dividers in the same state. Sixteen discrete phase rotations in 22.5? increments can be selected independently for each channel. For example, if Channel 1 is used as a reference and the RF signal applied to Channel 2 has an I/Q phase lead of 45?, Channel 2 can be phase aligned with Channel 1 by choosing the correct code.Phase shift is defined by the output of one channel relative to another. For example, if the code of Channel 1 is adjusted to 0000 and that of Channel 2 to 0001 and the same signal is applied to both RF inputs, the output of Channel 2 leads that of Channel 1 by 22.5?.The I and Q outputs are provided as currents to facilitate summation. The summed current outputs are converted to voltages by a high dynamic-range, current-to-voltage (I-V) converter, such as the AD8021, configured as a transimpedance amplifier. The resultant signal is then applied to a high resolution ADC, such as the AD7665 (16 bit/570 kSPS).The two I/Q demodulators can be used independently in other nonbeamforming applications. In that case, a transimpedance amplifier is needed for each of the I and Q outputs, four in total for the dual I/Q demodulator.The dynamic range is 159 dB/Hz at each I and Q output, but the following transimpedance amplifier is an important element in maintaining the overall dynamic range, and attention needs to be paid to optimal component selection and design.The AD8333 is available in a 32-lead LFCSP (5 mm ? 5 mm) package for the industrial temperature range of ?40?C to +85?C.Applications Medical imaging (CW ultrasound beamforming) Phased array systems (radar and adaptive antennas) Communication receivers
