Product introduction:
GF352102ME-618 is a Si-based switch filter multifunctional 3D integrated device with a operating frequency range of 6GHz~18GHz. It selects the filter channel through switch switching, amplifies the output through LNA amplifier, and integrates a coupler into the input port for signal amplification. It has microwave signal online detection function. This device is manufactured using si-based MEMS 3D integration technology, with multi-layer stacking achieved through wafer bonding and embedded GaAs MMIC chips, enabling external microwave signal transmission, power control, and microwave grounding. This device can be controlled using TLL level, with DC coupling between input and output terminals and matched to 50 Ω. It has the characteristics of low insertion loss, good flatness, and high out of band suppression within the operating frequency range. The product is mainly used in broadband microwave signal processing systems, and it is housed in a Si-based BGA package, suitable for SMT.
