Tahoe RF Semiconductor Inc.'s TRFS-151 CDMA RF receiver front-end and TRFS-201 integrated VCO IP blocks are targeted for use in multiple wireless communication standards.

The 900MHz RF front-end incorporates a dual-gain low noise amplifier and a dual-gain down conversion mixer. With off-chip filtering, the TRFS-151 provides the circuitry required to implement the front-end of the IS-98B CDMA standard for cellphones.

The TRFS-201 is a low phase noise CMOS, fully integrated VCO that operates from a 3V supply while drawing 5mA. It can be modified to operate at various center frequencies and is available with an integrated output buffer for standalone use. The IP block has a core circuitry that occupies a footprint <0.36mm?. Target applications include GSM, CDMA, WLAN, GPS, PCS/DCS, and AMPS wireless standards.

Both IP blocks are members of the company CoreTech product line and are manufactured using Jazz Semiconductor's 0.35?m SiGe BiCMOS process.
