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.

Operating Instructions
This device is static sensitive. Please handle with care. To operate the device, follow these steps. 1. Apply VGG = -4 V, VEE = -4V, VDD= 0 V. 2. Ramp VDD to desired voltage, typically 5 V. 3. Adjust VGG to set IDQ, (approximately @ –4V). 4. Set RF input. 5. Power down in reverse. Turn gate voltage off last.
