Description

The SA9504 is an integrated receiver front-end for 900 MHz Cellular (AMPS) and 1.9 GHz PCS (CDMA) phones. This dual-band receiver circuit has low noise amplifiers and downconverters for both bands, and SA9504 provides an elegant solution for RF-to-IF conversion.

The two cascode LNAs SA9504 have been designed to provide high gain with very low noise figures and high linearity. The downconverter portion is based on the Philips SA9502. There are two individual mixer blocks, each optimized for low noise figure and high linearity. The whole circuit of SA9504 is designed for low power consumption, high performance, and is compatible with the requirements for Cellular (AMPS) and PCS (CDMA) handsets.

The SA9504 has been designed in our advanced QUBiC3 BiCMOS process with 30 GHz fT and 60 GHz fMAX.
