ERI CF103 Low Power FM Group Delay Equalizer

The ERI Model CF103 Low Power FM 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 1.8 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.
