Philips UAA3580

The UAA3580 is a BiCMOS integrated circuit receiver intended for the Third Generation Partnership Project (3GPP) specification for the Universal Mobile Telecommunication System (UMTS). The circuit is specially designed for the Frequency Division Duplex (FDD) mode of the Wide Code Division Multiple Access (WCDMA) that operates in the 2110 to 2170 MHz band. The UAA3580 contains the whole analog receive chain from Radio Frequency (RF) Low Noise Amplifier (LNA) to baseband IQ outputs including a channel filter, a complete RF Phase-Locked Loop (PLL) with a fully integrated Voltage Controlled Oscillator (VCO), and a clock PLL that generates a programmable UMTS system clock from an external 26 MHz reference signal.
