SAN DIEGO--(BUSINESS WIRE)--July 26, 2000

Surface-mount Devices Ensure Uniform Signal Transmission With Wide

Frequency Bandwidth and Extremely Flat Frequency Response

Addressing the compact size requirements of advanced radio frequency (RF) communication equipment, Pulse announces a new line of miniature RF transformers, the CX2039, CX2040, and CX2047.

This family is available in a variety of impedance ratios and operates over wide frequency bandwidths while maintaining a flat frequency response. These small, surface-mount transformers are used to match impedances, step-up/step-down voltages, create DC isolation, as well as convert the circuit from balanced to single-ended. The miniature package makes these transformers ideal for space-constrained RF applications including cable modems, set-top boxes, wireless and cable network infrastructure equipment, and other high-frequency communication systems and Internet devices.

Technical Information

Each surface-mount transformer uses minimal board space, .15 x .15 inches (3.81 x 3.81 mm), and operates within a wide frequency bandwidth from 500KHz to 1.5 GHz. The family of products is available with 1:1 and 1:4 impedance ratios. Transformers are available with and without centertaps, and both DC-isolating and non-DC-isolating configurations. Further enhanced by excellent return loss, the CX2039, CX2040, and CX2047 are well-suited for many RF designs.

Pricing and Availability

These transformers are available in trays or tape-and-reel packaging. Depending on model, prices begin at $0.99 each, in quantities of 10,000. Other volume discounts are available. Details for all three products are listed in data sheet C203 available at http://www.pulseeng.com/pdf/2203.pdf.> About Pulse
