• GaAs MESFET

Description

The power amplifier module is designed for base stations and cell extenders

as cellular and GSM , IMT-2000, ISM, MMDS frequency systems.

GaAs MESFET is used and attached on a copper sub carrier. It is connected by

using bias and in/out matching circuit method with gold wire bonding.

The bias and matching circuit are designed much simpler than other circuits for silicon IC’s, LDMOS because

GaAs MESFET is operated by low supply voltage whereas others are operated by high supply voltage. 5

For better thermal conductivity, enhanced mode PCB was used in the 99.9% copper gold plate heat sink.

This simplicity results cost competitiveness and performance enhancement.
