Description
This digital radio transmitter
module is designed for medium
data rate point to point communi-
cation systems operating at
23␣ GHz. This module offers
excellent phase noise perfor-
mance and can be easily phase
locked to a frequency reference.
The transmitter module provides
+20 dBm of output power, ideal
for use in radios using 2 and 4
level FSK modulation. The module
features an ultra low noise silicon
bipolar VCO operating in the S/C
band. A portion of the oscillator
output is coupled off and is
applied to a frequency divider
network.

Detector
The low frequency output (less
than 1 GHz) from the frequency
divider can be easily used to
phase lock the source. The main
oscillator output is applied to a
frequency multiplier network to
produce the desired output
frequency in the 23 GHz range.
The output of this network is
filtered then amplified by a GaAs
MMIC device to produce the
required output power. A detected
sample of the output signal is
provided to facilitate built in test
of key radio components.
Applications
This digital radio module supplies
the transmitter function in radios
operating in the 21.2 to 23.6␣ GHz
band. The source provides close
to 100 mW output power over the
temperature range of -30°C to
+70°C. Included within the
transmitter module is a muting
function to reduce output power
by 50 dB for “hot standby” appli-
cations. An internal voltage
controlled attenuator function is
optional allowing for 30 dB
dynamic range adjustment.
