Bi-directional amplifier system for radio communication

摘要

An amplifier system is provided that can be coupled between a handset and an antenna of a radio frequency (RF) satellite-network communication system. The amplifier system includes a first signal path for amplifying an RF signal received at the antenna when the amplifier system has power supplied thereto. A second signal path is created through the amplifier system when a transmission signal is generated at the handset and the amplifier system has power supplied thereto. A third signal path is created through the amplifier system when no power is supplied thereto. When the third signal path is created, the first signal path and second signal path are disrupted, while the third signal path couples the handset to the antenna.

1. An amplifier system adapted to be coupled between a handset and an antenna of a radio frequency communication system, said amplifier system comprising:
a first signal path amplifying an RF signal received at the antenna and adapted to route said amplified RF signal to the handset when said amplifier system has power supplied thereto; a second signal path created when a transmission signal is generated at the handset wherein said first signal path is disrupted, said second signal path amplifying said transmission signal and adapted to route said amplified transmission signal to the antenna when said amplifier system has power supplied thereto; and a third signal path created when no power is supplied to said amplifier system wherein said first signal path and said second signal path are disrupted, and wherein said third signal path is adapted to couple the handset to the antenna.
