Latest Patents
Lee Phelps holds a patent for a "Complete outdoor radio unit for LMDS." This invention is a lightweight, compact transceiver that features planar circuitry. The transceiver utilizes cross polarization through an orthomodal transducer and frequency offset between transmit and receive to ensure isolation between the transmitter and receiver. It includes three printed circuit boards that are thermally conductive epoxy attached to a heat sink, which is part of the antenna dish/transceiver housing for effective heat transfer. The design incorporates two waveguides as receiver and transmitter transmission lines into the orthomodal transducer, while two additional waveguides serve as bandpass filters. Furthermore, the transceiver is equipped with a DC-DC converter in the power supply, modified to connect the base plate to the heat sink for compactness and improved heat transfer. A frequency synthesizer with a phase-locked loop is hardwired to a single reference frequency, contributing to the compact size of the device.
