Dual-duplexed, tower-top front-end for a radio transceiver system
First Claim
1. A front-end system for a communication station wherein the front-end system handles both reception signals collected via an antenna and transmission signals generated by the communication station for transmission via the antenna, comprising:
- a cryostat;
a receive path carrying the reception signals and disposed in the cryostat;
a transmit path carrying the transmission signals;
a first coupler that couples the receive path and the transmit path to the antenna and includes a phase-adjusting portion such that the transmission signals are not carried by the receive path;
a cable for carrying the reception signals and the transmission signals to and from the communication station, respectively; and
a second coupler that couples the receive path and the transmit path to the cable and includes a phase-adjusting portion such that the transmission signals are not carried by the receive path.

Abstract
A system handles both reception signals collected via an antenna and transmission signals generated by a communication station for transmission via the antenna. The system includes a cryostat, a receive path carrying the reception signals and disposed in the cryostat, and a transmit path carrying the transmission signals. The receive path and the transmit path are coupled between the system and the antenna and between the system and the communication station. Accordingly, the receive path is duplexed with the transmit path such that the front-end system has a first single input/output connection for coupling the front-end system to the antenna and a second single input/output connection for coupling the front-end system to the communication station.
