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
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.
Primary Applications
♦ 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, low-
noise, switch and digital FETs on a single chip, and polyimide
scratch protection for ease of use with automated manufactur-
ing processes. The use of refractory metals and the absence
of platinum in the gate metal formulation prevents hydrogen
poisoning when employed in hermetic packaging.

Operating Instructions
This device is static and light sensitive. The digital
circuitry operation can be impaired under high intensity
light, e.g. microscope light. Please handle with care.
To operate the device, follow these steps.
1. Power Up: Apply VEE = -5 V.
2. Apply TTL Levels to control pads as listed in
Recommended Operating Conditions
3. Power Down: Set VEE = 0

Assembly Instructions:
Die attach: Use AuSn (80/20) 1-2 mil. preform solder. Limit time @ 300 °C to less than 5 minutes.
Wirebonding: Bond @ 160 °C using standard ball or thermal compression wedge bond techniques.
For DC pad connections, use either ball or wedge bonds. For best RF performance, use wedge
bonds of shortest length, although ball bonds are also acceptable.
