Tunable AM/FM antenna amplifier has tunable frequency-selective input stage for FM signals, operates independently of standard FM receiver stage, can operate in remote configurations

摘要

The amplifier active circuit module has a tunable frequency-selective input stage for signals in the FM band and operates independently of the standard FM receiver stage and is hence suitable for operation in spatially remote configurations. The frequency selection leads to an output signal spectrum with a definitely lower bandwidth than the input signal spectrum
