In transmitters, solid state power amplifiers are needed to produce the RF power required to broadcast the desired signal at the correct power level. In portable and handheld applications, the RF power may be milliwatts to watts, depending on the application. In space and terrestrial fixed/mobile applications, required power output ranges from watts to many kilowatts. Power amplifiers for low power applications are usually straightforward designs. High power (up to kilowatts) usually involves close integration with power supplies, thermal management, RF power control and fail-safe circuits.

We have carried out high power designs for customers in L and S-Band using GaN, LDMOS and GaAs devices. Our low power designs have gone up to Ka-Band.
