Abstract

An RF (radio frequency) combiner utilizes RF filtering cavities and transmission paths incorporated into an RF impervious material. This allows traditional stand-alone multiplexers to be integrated into a single device without using signal loss-inducing cables and connections between the multiplexers. The simplicity of the RF combiner allows for RF filters to be milled out of the same RF impervious material without requiring an external RF connection and avoids a cascading of multiple RF filters. In one instance, the RF combiner is employed with two BTS (base transceiver stations) to allow the sharing of antennas without the power losses associated with traditional cascading duplexers.
