Infineon Targets RFICs at Mobile Designs

San Jose, CA-based Infineon Technology, formerly Siemens Microelectronics, has introduced a family of RFICs expressly designed for mobile applications. Compliant with CDMA, TDMA, and GSM specifications, the new product family includes single and dual phase locked loop (PLL) frequency synthesizers, universal and dual-band RF mixers/modulators, and a series of low noise amplifiers (LNAs).

Infineon's single PLL frequency synthesizer, dubbed the PMB 2341, is housed in a 3 x 5 mm TSSOP-10 package, operates up to 2.5 GHz, and features a phase noise performance of -87 dBc/Hz at 900 MHz (500 Hz offset). The PMB 2347 dual PLL, on the other hand, sports a TSSOP-20 package, processes IF signals up to 500 MHz and RF signals up to 2.8 GHz, and offers a similar sensitivity to the PMB 2341.

Housed in a TSSOP-10 package, the PMB 2335 universal RF mixer runs at frequencies up to 3 GHz, making it well suited for a range of RF and wireless designs. The two dual-band products, on the other hand, are specifically targeted at GSM 900/1800 (PMB 2362) or cellular/PCS 800/1900 (PMB 2363) applications. Both dual-band mixers are used in RF front-end designs, are equipped with 50 W impedance, and feature a TSSOP-10 footprint.

The PMB 2212 direct modulator rounds out the new family of RFICs. This modulator delivers an integrated mixer and an automatic gain control (AGC) with a 40 dB dynamic range. The IC operates at frequencies from 0.8 to 1.5 GHz and is housed in the TSSOP-24 fine-pitch package (fine pitch).

Samples of the new products are now available with mass production slated for the third quarter of 1999. For pricing information, contact Infineon at 408-501-6000.
