A complete procedure for the design of W-band low noise amplifier in MMIC technology is presented. The design is based on a simultaneously power and noise matched technique. For implementing the method, scalable bilateral transistor model parameters should be first extracted. The model is also used for transmission line utilized in the amplifier circuit. In the presented method, input/output ma...

In this paper, we have developed a high power solid-state power amplifier (SSPA) for Sband military radars. The SSPA consists of a high power amplifier (HPA) module combined GaN based power amplifier pallets, a drive amplifier (DA) module, a digital control module and a power supply unit. The SSPA shows the total output power of 62 dBm in S-band.

In this paper, power amplifier operating with center frequency of 947.5 MHz, which can be used for the transmitter in beamforming systems, is proposed. The power amplifier implemented provides high power added efficiency (PAE) of 71.967% and low noise figure (NF) as low as 1.525. The linearity of the power amplifier is improved by using square law and cubic law analog predistortion techniques. ...

A digital look-up table adaptive predistortion technique using a six-port receiver for power amplifier linearization is presented. The system is designed in Ka-band for a DVB-S2 satellite link. We use a six-port receiver at the linearizationloop in place of classic heterodyne receivers. The six-port receiver is implemented by the use of passive microwavecircuits and detector diodes. This approa...
