Abstract
The present invention is a modular frequency division filter having an antenna port that connects to two or three transmission paths. Each transmission path includes either a band pass filter or a duplexer to separate the received signal by frequency. Frequency phase shifters or shunt inductors may be included to further enhance the frequency separation. Following frequency separation, the separated signal is transceived by a device operating at the respective separated frequency.
