Description

This digital radio receiver module
provides the RF receive and down
conversion function for 23 GHz
digital radios. These modules offer
excellent phase noise perfor­mance and can be easily phase
locked to a frequency reference.
The receiver module provides an
output power of 3␣ dBm at the IF
frequency and is ideal for use in
radios using 2 and 4 level FSK
modulation. The excellent low
noise figure is achieved by using
the Hewlett-Packard PHEMT
MMIC technology coupled with an
image reject mixer. The receiver
module features an integrated
ultra low noise silicon bipolar

MMIC

X2A

VCO operating in the S/C band as
the local oscillator. A portion of
the oscillator output is coupled off
and is applied to a frequency
divider network. The low fre­quency output from the frequency
divider can then be easily used to
phase lock the source. The local
oscillator output is applied to a
frequency multiplier network to
produce the desired LO frequency
to the mixer.

Applications

This digital radio receiver module
provides the total RF receive and
down conversion function in
radios operating in the 21.2 to

23.6␣ GHz band.
