Description
The MA03503D is a parallel control input phase shifter/attenuator/buffer
amplifier MMIC. The on-chip driver circuitry allows for control of the 6 phase
and 5 attenuation bits using TTL/CMOS compatible voltage levels, and elimi-
nates the need for complementary inputs. 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 reli-
able GaAs Multifunction Self-Aligned Gate (MSAG^®) Process, each device
is 100% RF tested on wafer to ensure performance compliance.
Primary Applications
♦ Radar Systems
M/A-COM’s MSAG process features robust silicon-like manufacturing proc-
esses, planar processing of ion implanted transistors, multiple implant capa-
bility 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.
