Our high power radio frequency amplifiers and systems are engineered and produced to meet the most challenging performance requirements. KeyLink Microwave has been the preferred supplier in the worldwide radio frequency power amplifier industry and will always focus on your high performance RF microwave power amplifiers application needs.
Solid state power amplifier system is a electronic amplifier which using solid state devices including GaN, GaAs, LDMOS and bipolar device technologies for jamming, test and measurement, communication, radar and other rf and microwave industry.
A complete of GaN amplifiers from KeyLink offer excellent performance. Our GaN rf power amplifiers rang in output power from 2 - 200 watts with microprocessor based designs that incorporate an adaptive biasing algorithm to optimize efficiency and output power across the frequency band under varying load conditions.
The RF wideband amplifier subsystem KB0727S52A from KeyLink Microwave is a rack-mountable unit incorporating a universal voltage power supply and a built-in forced air-cooling amplifier system. This wideband amplifier subsystem operates from 700 MHz to 2700 MHz. It can handle an input power of up to 150 W and has a 50 ohm input/output impedance.
RF solid state power amplifier, which is basically the positive feedback system in our RF system, is generally located on the transmission chain. Considering the link attenuation of wireless transmission, the transmitter needs to radiate enough power to obtain a relatively long communication distance. Therefore, the radio frequency amplifier is mainly responsible for amplifying the power to be large enough and then feeding it to the antenna for radiation. It is the core device in the communication system.
