DC-6.0 GHz Attenuator MAATGM0001-DIE RO-P-DS-3043 B Preliminary Information Features ♦ ♦ ♦ ♦ 6 Bit Attenuator Range 35dB Coverage, LSB = 0.56dB TTL Control Inputs MSAG™ MESFET Process Primary Applications ♦ Satellite Communication ♦ Phased Array Radar Description Primary Applications The MAATGM0001-Die is a 6-bit Attenuator with Parallel Input Control. This product is fully matched to 50 ohms on both the input and output. ♦ Satellite Communication ♦ Phased Array Radar 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 implant capability enabling power, lownoise, switch and digital FETs on a single chip, and polyimide scratch protection for ease of use with automated 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.
