Z-Communications is one of the largest domestic manufacturers of voltage-controlled oscillators for the commercial/consumer electronics marketplace. The company is also emerging as a supplier for higher integration solutions, which include compact phase locked loop modules. Z-Communications' experience covers frequencies from 40 megahertz to 15 gigahertz. It provides a variety of low-cost, high-performance signal source solutions that have become the de facto industry standards by which other solutions are measured. With the need for ultra-small voltage-controlled oscillators for the emerging wireless local area network market, Z-Communications launched the SMV Series of voltage-controlled oscillators in 1994. Z-Communications is located in San Diego.
