PS20063
Image Reject MOPLL with IF AGC Amplifier
Preliminary Information
DESCRIPTION
The PS20063 is a 3 band MOPLL with IF AGC amplifier. It
down-converts the RF channel to a standard IF with image
rejection, simplifying front-end filtering. This is followed by
a SAW filter and IF AGC amplification for the digital
channel. Each band consists of a low noise
preamplifier/mixer and local oscillator with an external
varactor tuned tank circuit. An IF level detector is included
for control of the RF AGC. The Take Over Point (TOP)
and time constant are both programmable.
The PS20063 has excellent signal level handling
performance in the presence of high level unwanted
signals.

All chip control is via an I C compatible interface.
An alternative part, PS20060, is available without image
reject down conversion.
