Title: Innovations of Paul L Brownlee
Introduction
Paul L Brownlee is a notable inventor based in Mesa, AZ (US). He has made significant contributions to the field of technology, particularly in the area of amplifier transceiver systems. With a total of 2 patents, his work showcases innovative solutions that enhance performance and reduce complexity in electronic systems.
Latest Patents
One of his latest patents is the "Complimentary switched amplifier transceiver system." This invention offers performance advantages over conventional half-duplex transceivers by utilizing complimentary switched amplifiers to eliminate switches. This design ensures that power output to a channel transition from a transmit amplifier is not degraded by switch insertion loss in transmit mode. Additionally, the receiver noise figure remains unaffected due to the absence of switch insertion loss from the channel transition to a receive amplifier. By eliminating switch devices and their associated control lines, Brownlee reduces circuit complexity for complimentary switched amplifier circuits.
Another significant patent is the "High frequency transition from a microstrip transmission line to an MMIC." This invention provides a high-frequency transition from a microstrip transmission line to an MMIC coplanar waveguide. The microstrip transmission line is representative of those typically found in high-frequency RF modules. The MMIC coplanar waveguide is designed for low-cost MMICs fabricated on a semiconductor substrate. The interface couples the microstrip transmission line to a mode converter, which provides impedance mismatch compensation and coplanar waveguide propagation mode conditions.
