International Manufacturing Services, Inc. (IMS) is now producing Temperature Variable Attenuators (TVAs) for a wide range of applications to 20 GHz and beyond. The new AV-0607-C TVAs are ideal for RF power amplifiers (PAs), broadcast equipment, and multiband communications systems. With their low-noise, thin-film construction, the TVAs exhibit decreasing attenuation with increasing temperature to help offset, loss of amplifier gain at higher frequencies and temperatures. They are supplied with well-defined temperature characteristics of attenuation (TCA) from 10 MHz to 20 GHz for designers seeking to simulate their impact on signal attenuation and gain in circuits and designs.
The AV-0607-C TVAs are available with attenuation ranges of 2 to 9 dB and power ratings of 160 to 200 mW from DC to 24 GHz. They maintain stable, accurate attenuation with temperature, with typical attenuation accuracy of ±1.0 dB from DC to 15 GHz and ±1.8 dB or better to 20 GHz and beyond. These 50-ohm SMT attenuators are available in a 0607 case that measures .060 × 0.075 × 0.043 in. making them ideal for the smallest and tightest RF designs.
The AV-0607-C TVAs maintain steady signal levels in harsh environments, including in the most demanding aerospace and defense (A&D) applications, such as radars and satellite communications (satcom) systems.
