IC Features Stepped Gain-Control Range And Adjustable IIP3

The RF2460 LNA/mixer is a complete receiver front-end chip for the PCS CDMA market. The mixer is a 3.0V complete receiver front end with gain, noise figure and IIP3 specifications designed to be compatible with the IS-98B standard for CDMA PCS handsets. The IC amplifies and downconverts RF signals while providing 29 dB of stepped gain control range and features digital control of LNA gain, mixer gain and power-down mode. The RF2460 meets or exceeds the requirements for US and Korean PCS CDMA handsets. It can also be used for other downconverter applications in the 1,500 to 2,200 MHz frequency range, such as W-CDMA. The RF2460 is manufactured using a SiGe HBT process and is offered in a small, 4x4 mm, MLF-20 leadless plastic package. The unit is priced at $1.89 each/10,000. Samples and fully assembled evaluation boards are available now, with production quantities available early in the second quarter of 2001.
