DC Power: 150 mA ## Function The AU-1421 is a medium power amplifier operating in the 1- 400 MHz frequency range. It provides RF amplification, typically boosting signal power for satellite communication systems. Input and output interfaces are waveguide, with DC power provided via a multi-pin connector. It features gain control and protection circuits for VSWR and temperature. Common applications are uplink and downlink systems. ## Platform Designed for RF and microwave systems, integrates into satellite communication systems, and connects via coaxial RF interfaces for signal amplification in frequency bands from 1- 400 MHz. ## Application Medium power amplifiers designed for broadband RF/microwave amplification in the 1- 400 MHz frequency range, providing approximately 150 mA output power with low noise figure. Commonly used as gain blocks, driver stages, or intermediate amplifiers in receiver and transmitter chains, enabling cost reduction by minimizing the number of amplification stages. Features include multi-octave bandwidth operation across L to K bands, built-in thermal protection with automatic reset, over/under current alarms, and electronic on/off control for integration in complex RF systems requiring reliable and efficient medium power amplification. ## Images - - - -
