GaAs MMIC integrated frequency conversion multifunction chip 2.5~5GHz

SAC3605 is a GaAs transceiver chip with Up -converter and Down-converter mixer function. It is integrated with RF bidirectional amplifiers, a LO drive amplifier, a double balanced mixer, switches, a low pass filter, and 3-bit digital controlled attenuators. It covers 2.55GHz RF and LO frequency range with IF frequency 0.651.5GHz. It generates 16dB conversion gain with typical 0 dBm LO input level.

The chip is back-metalized to ensure better grounding. It can be die-mounted with AuSn eutectic preform or with electrically conductive epoxy.
