GENERAL DESCRIPTION

The ADRF6516 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 desired 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 ADRF6516 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 15.5 mV/dB. Their

maximum gains can be programmed to various values through

the SPI. The output buffers provide a differential output impedance

of 30 Ω and are capable of driving 2 V p-p into 1 kΩ loads. The

output common-mode voltage defaults to VPS/2, but it can be

adjusted down to 700 mV by driving the high impedance VOCM

pin. Independent, built-in dc offset compensation loops can be

disabled if fully dc-coupled operation is desired. The high-pass

corner frequency is defined by external capacitors on the OFS1

and OFS2 pins and the VGA gain.

The filters provide a six-pole Butterworth response with 1 dB

corner frequencies programmable through the SPI port from

1 MHz to 31 MHz in 1 MHz steps. The preamplifier that precedes

the filters offers a SPI-programmable option of either 3 dB or 6 dB

of gain. The preamplifier sets a differential input impedance of

1600 Ω and has a common-mode voltage that defaults to VPS/2

but can be driven from 1.1 V to 1.8 V.

The ADRF6516 operates from a 3.15 V to 3.45 V supply

and consumes a maximum supply current of 360 mA when

programmed to the highest bandwidth setting. When disabled,

it consumes <9 mA. The ADRF6516 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.
