AD8333-EVALZ

Analog Devices Inc.
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

AD8319-EVALZ

Analog Devices Inc.
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

ADP2139CB-0.8EVALZ

Analog Devices Inc.
The ADP2138 and ADP2139 are high efficiency, low quiescent current, synchronous step-down dc-to-dc converters. The ADP2139 has the additional feature of an internal discharge switch. The total solution requires only three tiny external components. When the MODE pin is set high, the buck regulator operates in forced PWM mode, which provides low peak-to-peak ripple for power supply noise sensitive loads at the expense of light load efficiency. When the MODE pin is set low, the buck regulator automatically switches operating modes, depending on the load current level. At higher output loads, the buck regulator operates in PWM mode. When the load current falls below a predefined threshold, the regulator operates in power save mode (PSM), improving light load efficiency.The ADP2138/ADP2139 operate on input voltages of 2.3 V to 5.5 V, which allows for single lithium or lithium polymer cell, multiple alkaline or NiMH cell, PCMCIA, USB, and other standard power sources. The maximum load current of 800 mA is achievable across the input voltage range.The ADP2138/ADP2139 are available in fixed output voltages of 3.3 V, 3.0 V, 2.8 V, 2.5 V, 1.8 V, 1.5 V, 1.2 V, 1.0 V, and 0.8 V. All versions include an internal power switch and synchronous rectifier for minimal external part count and high efficiency. The ADP2138/ADP2139 have internal soft start and they are internally compensated. During logic controlled shutdown, the input is disconnected from the output and the ADP2138/ADP2139 draw 0.2 ?A (typical) from the input source.Other key features include undervoltage lockout to prevent deep battery discharge, and soft start to prevent input current overshoot at startup. The ADP2138/ADP2139 are available in a 6-ball wafer level chip scale package (WLCSP).Applications PDAs and palmtop computers Wireless handsets Digital audio, portable media players Digital cameras, GPS navigation units
