GENERAL DESCRIPTION
The ADRF6520 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 ADRF6520 ideal for
quadrature-based (IQ) communication systems with dense
constellations, multiple carriers, and nearby interferers. The
filter corners, enable, and dc offset correction loop enable are
all programmable via a serial peripheral interface (SPI).
The first VGA that precedes the filters offers 30 dB of continuous
gain control with a maximum gain of 18 dB and sets a differential
input impedance of 100 Ω. The filters provide a four-pole
Butterworth response with −1 dB corner frequencies: 36 MHz,
72 MHz, 144 MHz, 288 MHz, 432 MHz, 576 MHz, and 720 MHz.
For operation beyond 720 MHz, the filter can be disabled and
completely bypassed, thereby extending the −1 dB bandwidth
up to 1.25 GHz. A wideband rms detector is available to
monitor the signal at the filter inputs. A fixed gain amplifier of
6 dB immediately follows the filter. The postfilter VGA provides
30 dB of continuous gain control with a maximum gain of
12 dB. The output buffers offer an additional 18 dB of gain and
provide a differential output impedance of 20 Ω. The output
buffers are capable of driving 1.5 V p-p into 100 Ω loads at better
than 55 dBc nominal for the third-order intermodulation
distortion (IMD3). Independent, built in, dc offset correction
loops for each channel can be disabled via the SPI if fully dc-
coupled operation is desired. The high-pass corner frequency is
determined by external capacitors on the CHP1 and CHP2 pins
and the postfilter VGA gain.
The ADRF6520 operates from a 3.15 V to 3.45 V supply and
consumes a maximum supply current of 425 mA. When fully
disabled, it consumes ≤10 mA. The ADRF6520 is fabricated in
an advanced silicon-germanium BiCMOS process and is
available in a 32-lead, exposed pad LFCSP. Performance is
specified over the −40°C to +85°C temperature range.
