Description
M/A-COM's AM42-0046 is a three stage MMIC
power amplifier in a bolt down ceramic package,
allowing easy assembly. The AM42-0046 employs
a fully matched chip with internally decoupled gate
and drain bias networks. The AM42-0046 is
designed to operate from a constant current drain
supply or a constant voltage gate supply. By
varying the bias conditions, the saturated output
power performance of this device may be tailored
for various applications.
The AM42-0046 is ideally suited for use as an
output stage or a driver amplifier in VSAT systems.
The AM42-0046 includes internal supply line
bypassing in the
package, minimizing the number of
external components required.
M/A-COM's AM42-0046 is fabricated using a mature
0.5 micron MBE based GaAs MESFET process. The
process features full passivation for increased
performance and reliability. This product is 100% RF
tested to ensure compliance to performance
specifications.
