WJC introduces mixers for 3G wireless markets

May 4, 2005

WJ Communications, a supplier of RF solutions for the wireless infrastructure and RFID reader markets, introduced two new highly linear mixers, the MH103A and MH203A. Both mixers offer improved third-order intercept (IP3) and lower conversion loss and are ideal for WCDMA, CDMA2000, and multi-carrier applications.

"The MH103A and MH203A are the first monolithic integrated circuits in the marketplace with very high IP3s and low conversion loss comparable to the best discrete mixers on the market," said Ron Buswell, senior vice president of marketing and product line management for WJ Communications. "Current and next generation infrastructure systems require mixer solutions that deliver higher IP3 performance at a lower cost. We are providing our customers with these products. These mixers also offer lower conversion loss, improved dynamic range and are ideal for 3G applications. These products add to the broad range of RF components already offered by WJ, specifically for 3G wireless systems."

Product Overview

Among the key benefits of the MH103A and MH203A are high IP3, up to +34 dBm and a low conversion loss. The MH103A and MH203A are passive GaAs MESFET mixers that provide high dynamic range performance in a low cost SOIC-8 package. These devices use patented techniques to realize +34 dBm Input IP3 at an LO drive level of +17 dBm when used in transceiver applications as an up-converter or a down-converter. This single monolithic integrated circuit does not require any external baluns or bias elements. Typical applications include frequency up/down conversion, modulation and demodulation for receivers and transmitters used in 3G UMTS systems.
