Abstract:
This paper presents the design, simulation and
measurement of an S-band GaAs P-HEMT high linearity
amplifier. The amplifier is part of the down-converter in the
on-board satellite repeaters of an S-DMB system that provides
digital mobile broadcast/multicast services. The topology of the
amplifier has been chosen to achieve a high linearity, and a
wideband input matching network has been included in order
to obtain the required specifications without using any external
components. The S-band amplifier has been measured showing
an OIP3 of 23 dBm and a gain of 15.3 dB, obtaining also good
values of input and output matching. These results are obtained
in the first fabrication run of the circuit.
