Description
The
MA03501D
is a serial control input phase shifter/
attenuator/buffer amplifier MMIC. The on-chip serial to
parallel converter circuitry allows for control of the 6
phase and 5 attenuation bits using a single TTL/CMOS
compatable input. This product is fully matched to 50
ohms on both the input and output.
Each device is 100% RF tested on wafer to ensure
performance compliance. The part is fabricated using
M/A-COM’s repeatable, high performance and highly
reliable GaAs Multifunction Self-Aligned Gate (MSAG
®
)
MESFET Process.
