Overview
It is an X-band multifunction GaAs chip (MMIC) that integrates amplifiers, switches, six-bit attenuators, six-position phase shifters, control drivers, and more, 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 from a +4.3V/-2.9V power supply, the control level signal is TTL, and the phase shift attenuation is controlled in parallel.
