IF Amplification and Filtering Chip

Product introduction:

The GF35303ME-1323 intermediate frequency amplification and filtering chip integrates equalizer chip, gain block chip, filter chip, single pole double throw switch chip, digital attenuator chip, etc. It has achieved functions such as numerical control attenuation, amplification, and filtering of intermediate frequency signals. It is manufactured using silicon-based MEMS technology and multi-layer stacking is achieved through wafer bonding. It is housed in a silicon-based BGA package, suitable for SMT.
