WJ Communications Announces a High Dynamic Range CATV Amplifier; Improved Return Loss and Gain Performance.

SAN JOSE, Calif. -- WJ Communications, Inc. (Nasdaq:WJCI), a leading designer and supplier of RF semiconductors and multi-chip modules, today announced the availability of the AH22S, a high dynamic range amplifier targeting the CATV market. The AH22S combines superior gain flatness, high linearity, and broad bandwidth. These characteristics make it ideal for CATV distribution, cable modem, and laser diode driver applications.

"To meet our customers need for better performance, the AH22S exhibits improved gain, P1dB and IP2 performance. These aspects combine for optimal performance in meeting the stringent requirements for CATV systems worldwide," said Ron Buswell, senior vice president of marketing and product line management for WJ Communications. "The growth of the CATV market provides additional opportunities for WJ's portfolio of high dynamic range amplifiers and mixers. We are currently developing additional products to address CATV applications."

Product Overview

The AH22S uses two matched devices and is ideal for operation in a push-pull configuration to achieve low distortion characteristics at 39 dBmV/channel (77 channels). The push-pull amplifier is capable of achieving high performance levels of -74dBc CSO and -80dBc CTB above 100 MHz. A mature and reliable GaAs MESFET technology is employed to maximize linearity at low power distortion. The dual amplifier is housed in an industry standard surface-mount SOIC-8 package with all devices being 100% RF and dc tested. Compared to the existing AH22 product, this device offers improved VSWR and gain flatness and higher gain over the entire CATV frequency band depending on customers' applications.

Availability

The AH22S is scheduled for high-volume production worldwide. Sample quantities are available now and can be requested directly from the WJ web site (www.wj.com).
