Project Description

This Slipstream Design Solid State Power Amplifier is a high power extended efficiency Doherty Amplifier which operates from 1710 to 1785 MHz. Designed for high peak to average signals and pulsed CW applications, the amplifier is compact and robust making it suitable for communications systems that demand high reliability in a rugged environment.

Employing LDMOS technology, the P1bD output power is 130W over a temperature range of -20°C to +60°C. Standard features include reverse polarity protection, output short and open circuit protection as well as power supply sequencing.

Fully tested, this module is available for immediate off-the-shelf use or can be customised to meet your exact system and interface requirements.
