The AD8344 is a high performance, broadband active mixer. It is well suited for demanding receive-channel applications thatrequire wide bandwidth on all ports and very low intermodulation distortion and noise figure.The AD8344 provides a typical conversion gain of 4.5 dB at 890 MHz. The integrated LO driver supports a 50 ? inputimpedance with a low LO drive level, helping to minimize external component count.The single-ended 50 ? broadband RF port allows for easy interfacing to both active devices and passive filters. The RFinput accepts input signals as large as 1.7 V p-p or 8.5 dBm (re: 50 ?) at P1dB.The open-collector differential outputs provide excellent balance and can be used with a differential filter or IF amplifier,such as the AD8369 or AD8351. These outputs may also be converted to a single-ended signal through the use of a matchingnetwork or a transformer (balun).When centered on the VPOS supply voltage, each of the differential outputs may swing2.5 V p-p.The AD8344 is fabricated on an Analog Devices proprietary, high performance SiGe IC process. The AD8344 is availablein a 16-lead LFCSP package. It operates over a ?40?C to +85?C temperature range.An evaluation board is also available.ApplicationsCellular base station receiversISM receiversRadio linksRF Instrumentation

The AD8366 is a matched pair of fully differential, low noise and low distortion, digitally programmable variable gain amplifiers (VGAs). The gain of each amplifier can be programmed separately or simultaneously over a range of 4.5 dB to 20.25 dB in steps of 0.25 dB. The amplifier offers flat frequency performance from dc to 70 MHz, independent of gain code.The AD8366 offers excellent spurious-free dynamic range, suitable for driving high resolution analog-to-digital converters (ADCs). The NF at maximum gain is 11.4 dB at 10 MHz and increases ~2 dB for every 4 dB decrease in gain. Over the entire gain range, the HD3/HD2 are better than ?90 dBc for 2 V p-p at the output at 10 MHz into 200 ?. The two-tone intermodulation distortion of ?90 dBc into 200 ? translates to an OIP3 of 45 dBm (38 dBVrms). The differential input impedance of 200 ? provides a well-defined termination. The differential output has a low impedance of ~25 ?.The output common-mode voltage defaults to VPOS/2 but can be programmed via the VCMA and VCMB pins over a range of voltages. The input common-mode voltage also defaults to VPOS/2 but can be driven down to 1.5 V. A built-in, dc offset compensation loop can be used to eliminate dc offsets from prior stages in the signal chain. This loop can also be disabled if dc-coupled operation is desired.The digital interface allows for parallel or serial mode gain programming. The AD8366 operates from a 4.75 V to 5.25 V supply and consumes typically 180 mA. When disabled, the part consumes roughly 3 mA. The AD8366 is fabricated using Analog Devices, Inc., advanced silicon-germanium bipolar process, and it is available in a 32-lead exposed paddle LFCSP package. Performance is specified over the ?40?C to +85?C temperature range.ApplicationsBaseband I/Q receiversDiversity receiversWideband ADC drivers?

The AD8452-EVALZ is a platform for the AD8452, designed for investigation of the AD8452 analog and pulse-width modulation (PWM) features and performance without the added complications of a driver and/or switch mode power supply (SMPS) design. For convenience, a precision 5 V reference IC and four trim pots are built in to the evaluation board, for driving the battery current and voltage ISET and VSET inputs. All device pins are accessible with test loops or probe landings. At the same time, the AD8452-EVALZ has the flexibility to interface and drive a typical half bridge inductor input SMPS with output levels in the 1 A to 15 A range. SMPS and associated components are specified and sourced by the user. The AD8452 is intended for use as the core controller for commercial battery test and formation systems.
