Overview
It is a multifunctional GaAs chip (MMIC) that integrates amplifier, switch, six-bit attenuator, six-position 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 from a +5V/-5V power supply, the control level signal is TTL, and the phase-shift attenuation is serial controlled.
