AM77

Utilising the latest GaN transistor technology, AM77 amplifiers are designed for X-Band RADAR applications up to 200W of Pulsed Power. This model is suitable for use in weather monitoring systems including rainfall measurement, with pulsed signals up to 100uS with 10% duty. Mechanically robust and with protection circuits to ensure long-term reliability, the amplifier is supplied in modular form for OEM system integration.
