Description
The MAATGM0001 is a 6-bit Attenuator with Parallel Input Control. This
product is fully matched to 50 ohms on both the input and output.
Fabricated using M/A-COM’s repeatable, high performance and highly
reliable GaAs Multifunction Self-Aligned Gate MESFET Process, each
device is 100% RF tested on wafer to ensure performance compliance.
M/A-COM’s MSAG™ process features robust silicon-like manufacturing
processes, planar processing of ion implanted transistors, multiple im-
plant capability enabling power, low-noise, switch and digital FETs on a
single chip, and polyimide scratch protection for ease of use with auto-
mated manufacturing processes. The use of refractory metals and the
absence of platinum in the gate metal formulation prevents hydrogen
poisoning when employed in hermetic packaging.
Primary Applications
♦ Satellite Communication
♦ Phased Array Radar
