Description

M/A-COM’s AM42-0039 is a three-stage MMIC power
amplifier in a ceramic bolt down style hermetic package. The
AM42-0039 employs a fully matched monolithic chip with
internally decoupled Gate and Drain bias networks. The
AM42-0039 is designed to be operated from a constant current
Drain supply. By varying the Gate bias voltage, the saturated
output power performance of this device can be tailored for
various applications.

The AM42-0039 is designed for use as an output stage or driver
amplifier for VSAT transmitter systems. This amplifier is
monolithic and requires a minimum of external components.

M/A-COM’s AM42-0039 is fabricated using a mature 0.5
micron GaAs MESFET process. The chip is fully passivated for
increased performance and reliability. These amplifiers are
100% RF tested to ensure compliance to performance
specifications.
