The Model CF103 Low Power Group Delay Equalizer provides
group delay pre-correction for FM transmitters at low level,
usually between the FM transmitter’s exciter and intermediate
power amplifier. The pre-correction applied offsets excess
group delay variation and asymmetry that is unavoidable in
FM combiner systems that include closely spaced frequencies,
of 1.0 MHz or less. The CF103 has a power rating of 150 watts
and provides up to one microsecond of correction across a
single FM broadcast channel. ERI also has available group
delay equalizers that operate at high power, which offer
greater correction range and are located directly before each
individual station’s combining module. This means that the
proper correction applied regardless of whether the main
or auxiliary transmitter is on-line and it is not affected by
transmitter supply voltage variations or changes in output
Note: Requires two (2) interconnecting coaxial cables, not supplied: one from the FM transmitter exciter output to the input of the CF103 and one from the output of the CF103 to the input of the FM transmitter IPA. These are optionally available from ERI.
