Abstract

The design of a harmonic filter and an antenna switch for a two-way mobile radio system is reported here. The harmonic filter is a filter that makes sure that the higher order harmonics from the power amplifier stage are sufficiently attenuated so the transmitted signal is as pure as possible. Then an antenna switch must switch between transmitter and receiver in a half-duplex radio. In this work, the design of a harmonic filter and an antenna switch that meet the TIA specifications is reported. The ADS based design has been prototyped and tested. Some optimization has been performed to improve the radio performance
