Description
The UPB121D is a silicon monolithic integrated circuit for GPS receivers. It is designed as a double conversion RF block integrated pre-amplifier, RF/IF down-converter, and PLL frequency synthesizer on a single chip. This IC also includes an IQ recovery function and a 2-bit A/D converter in both I and Q channels. The UPB121D is manufactured using a 30 GHz fmax UHS0 silicon bipolar process and is packaged in a 36-pin plastic QFN package.
