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.
