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.
