Overview
It is a multifunctional GaAs chip (MMIC) that integrates amplifier, switch, six-bit attenuator, six-bit phase shifter, control driver and more, and is fabricated using a gallium arsenide pseudo-high electron mobility transistor (PHEMT) process. The chip is grounded via a through-hole via metal on the back. All chip products are 100% RF measured. The chip operates with a +5V/+5V/-5V power supply, TTL control level signal, and parallel control of phase shift attenuation.
