Power-amplifiers - AM61/9.7S-20-61---Pulsed-Power

The series AM61 covers frequencies of 9.71GHz to 9.73GHz and has a maximum output power of 1400 watts

 

Product Series: AM61

1.4kW X-Band Solid-State Power

Utilising the latest GaN transistor technology, AM61 amplifiers are designed for X-Band RADAR applications. Two power modules each containing four 200W transistors are combined in waveguide. This model is suitable for use in weather monitoring systems including rainfall measurement, with pulsed signals up to 100uS with up to 10% duty given sufficient cooling. Mechanically robust and with protection circuits to ensure long-term reliability, the amplifier is supplied in modular form for OEM system integration.
