WJ Communications Expands CATV Mixer Product Line; Suitable for DOCSIS 2.0 System Requirements.

SAN JOSE, Calif. -- WJ Communications, Inc. (Nasdaq:WJCI), a leading designer and supplier of RF semiconductors and multi-chip modules, today announced the addition of the HMJ7-1, a new high dynamic range GaAs FET mixer ideally suited for DOCSIS 2.0 CATV head-end equipment. The HMJ7-1 provides enhanced suppression of intermodulation products needed for higher performance CATV applications.

"The introduction of the HMJ7-1 is optimized for customers looking for a high-performance device designed to meet the strenuous requirements for the DOCSIS 2.0 and Euro DOCSIS standards," said Ron Buswell, senior vice president of marketing and product line management for WJ Communications. "This product broadens WJ's industry-leading CATV mixer portfolio and serves as another example of the advantages of the flexible manufacturing platforms that we have."

Product Overview

The HMJ7-1 is an active broadband mixer which realizes an OIP3 greater than +34 dBm at an LO drive level of +24 dBm. The HMJ7-1 provides excellent suppression of spurious intermodulation products, of greater than 67 dBc, meeting DOCSIS 2.0 and Euro DOCSIS system requirements. Product features include a -77 dBc 2x1 spur rejection in IF band, RF and LO frequency range of 1000-2000 MHz, and IF frequency range of 10-1000 MHz. The HMJ7-1 comes in a low-cost, 22-pin J-Lead package. The combination of high dynamic range and spurious suppression makes the HMJ7-1 an ideal choice for CATV headend transmission equipment and other applications requiring a broadband mixer in the 1000 MHz to 2000 MHz frequency range.
