Abstract: The design of a highly linear microwave driver amplifier is presented. The design uses the latest commercial, off‐the‐shelf components, rather than unique, research devices. Cost‐effective, general‐purpose broadband devices from WJ Communications have been employed. The driver amplifier design is optimized for the satellite communications transmit band, 1626.5–1660.5 MHz. The circuit reported would be of interest to RF designers working on L‐band satellite communications transceivers or designers interested in issues involved in the use of commercial devices designed for terrestrial applications.
