  • Patent number: 8666342
    Abstract: A circuit for a reflection-type variable attenuator may include a hybrid module including an input port, an output port, a first reflection port, and a second reflection port. The hybrid module may be configured to split an incident signal received at the input port into a first and a second input signal.

  • Patent number: 8610832
    Abstract: Disclosed herein are systems, methods, and computer-readable storage media for broadcasting signals. The system includes a supplemental antenna at a first location co-located with a main antenna transmitting a main signal. The supplemental antenna is physically separate from a main antenna at the same location and transmits a supplementary signal adjacent to the main signal which matches or corresponds to a remote signal transmitted from an antenna at a remote location. The system transmits the supplemental signal at sufficient power to overcome interference in a coverage hole of the remote signal caused by the main signal. A supplemental antenna co-located with the main antenna can transmit the supplemental signal. The system can receive a supplemental signal that matches a remote signal, pass the supplemental signal through a same power amplifier and filter as a local main signal, and broadcast via an antenna both the main signal and the supplemental signal.
