New Double-Balanced Mixers Deliver IIP3 up to +40 dBm. New High Linearity Mixer Family is Ideal for Cellular/4G Infrastructure Transceivers.

Chelmsford, MA, July 17, 2009 - Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has introduced two new SiGe BiCMOS MMIC Mixer RFICs which are ideal for upconversion and downconversion applications in broadband, Cellular/3G, WiMAX/4G and test equipment applications from 700 MHz to 2.2 GHz.

The HMC785LP4E and HMC786LP4E are SiGe BiCMOS Mixer RFICs which are rated from 0.7 to 1.1 GHz and 1.7 to 2.2 GHz, respectively. Both products consist of a high linearity double-balanced mixer core and a matched local oscillator (LO) amplifier which combine to deliver up to +40 dBm input IP3 with only 0 dBm of input LO drive. The HMC785LP4E and HMC786LP4E feature singled-ended LO and RF ports, while the differential IF ports support intermediate frequencies from 50 to 300 MHz. The HMC785LP4E and HMC786LP4E are optimized for high side and low side LO inputs respectively, and exhibit conversion loss as low as 7.5 dB with up to 30 dB of LO to RF and LO to IF isolation. These compact mixer RFICs are ideal for upconversion and downconversion applications in GSM, WCDMA, TD-SCDMA, WiBro and WiMAX.

The HMC785LP4E and HMC786LP4E are housed in footprint compatible RoHS compliant leadless 4x4 mm QFN SMT packages, operate from a single +5V supply, and are ideal for cellular/3G and WiMAX/LTE/4G infrastructure applications.

Samples and evaluation PC boards for all SMT packaged products are available from stock and can be ordered via the company’s e-commerce site or via direct purchase order. Released data sheets are available on-line at www.hittite.com.
