GENERAL DESCRIPTION

The ADRF6510 is a matched pair of fully differential low noise

and low distortion programmable filters and variable gain ampli-

fiers (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 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 ꢀ that is

capable of driving 1.5 V p-p into 1 kꢀ 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 pro-

grammed 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.

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 imped-

ance 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.
