Latest Patents
Peter Chu's latest patents include a high power prematched MMIC transistor with improved ground potential. This multicell transistor is designed for use in circuits and features an input ground plane for an input waveguide and an output ground plane for an output waveguide. The design includes a gate electrode coupled to the input waveguide, a drain electrode coupled to the output waveguide, and a source electrode connected to the input ground plane. Additionally, an output ground strap is spaced from the drain electrode to couple the output ground plane to the source electrode. The invention also incorporates a pair of transmission lines that are orthogonally connected to the gate electrode, forming inductors for impedance matching.
Another significant patent is the heterojunction bipolar transistor structure having low base-collector capacitance. This innovation reduces the base-collector capacitance in a heterojunction bipolar transistor, which enhances cutoff frequency and power gain. The design eliminates a portion of the collector contact layer that typically underlies the base electrode. Furthermore, a ballast resistor layer is formed between the emitter layer and the overlying emitter electrode to prevent thermal runaway and hot spot formation. This technology can be arranged in a distributed amplifier configuration, providing high thermal efficiency and optimal circuit matching characteristics.
