Product introduction:
GF352103ME-618 is a Si-based switch filter mixing multifunctional 3D integrated device, which integrates chip circuits such as microwave switches, high-performance MEMS bandpass filters, mixers, and amplifiers. The module inputs signals ranging from 6GHz to 18GHz, selects one of the four switch filter banks through a switch for filtering, and then down converts them to 1.3GHz to 2.3GHz through a mixer before final output. This device has bidirectional transmission and reception capabilities. This device is manufactured using Si-based MEMS 3D integration technology, with multi-layer stacking achieved through wafer bonding, it is housed in a Si-based BGA package, suitable for SMT.
