The ADRF6510 is a matched pair of fully differential low noise and low distortion programmable filters and variable gain amplifiers (VGAs). Each channel is capable of rejecting large out-of-band interferers while reliably boosting the wanted signal, thus reducing the bandwidth and resolution requirements on the analog-to-digital converters (ADCs). The excellent matching between channels and their high spurious-free dynamic range over all gain and bandwidth settings make the ADRF6510 ideal for quadrature-based (IQ) communication systems with dense constellations, multiple carriers, and nearby interferers.
The filters provide a six-pole Butterworth response with 0.5 dB corner frequencies programmable through the SPI port from 1 MHz to 30 MHz in 1 MHz steps. The preamplifier that precedes the filters offers a pin-programmable option of either 6 dB or 12 dB of gain. The preamplifier sets a differential input impedance of 400 Ω and has a common-mode voltage that defaults to 2.1 V but can be driven from 1.5 V to 2.5 V.
The variable gain amplifiers that follow the filters provide 50 dB of continuous gain control with a slope of 30 mV/dB. The output buffers provide a differential output impedance of 20 Ω that is capable of driving 1.5 V p-p into 1 kΩ loads. The output common-mode voltage defaults to VPS/2, but it can be programmed via the VOCM pin. The built-in dc offset correction loop can be disabled if dc-coupled operation is desired. The high-pass corner frequency is defined by external capacitors on the OFS1 and OFS2 pins.
The ADRF6510 operates from a 4.75 V to 5.25 V supply and consumes a maximum supply current of 258 mA when programmed to the highest bandwidth setting. When disabled, it consumes 2 mA. The ADRF6510 is fabricated in an advanced silicon-germanium BiCMOS process and is available in a 32-lead, exposed paddle LFCSP. Performance is specified over the −40°C to +85°C temperature range.
