Abstract :
The aim of this paper is to present results of a 2 GHz amplifier´s output power calculations, up to phase of load reflection coefficient at 4 GHz and 6 GHz frequency. The amplifier is based on two MESFET devices, each having a 3.6 mm gate width and 2 GHz operating frequency. Contours of maximum and minimum output power have been determined. This paper describes the method of design of the amplifier´s output circuit with frequency crossing 2:1 (2-4 GHz), which gives a high output power at 4 GHz without additional power loss, which is linked to the load phase at the second harmonic.
