The WTVA Series from Smiths Interconnect are Temperature Variable Chip Attenuators that operate from DC to 20 GHz. They are available in attenuation values from 2 to 7 dB with 1 dB increments and an accuracy of ± 0.5 dB. The attenuators have a Temperature Coefficient of Attenuation (TCA) from -0.003 to -0.007 dB/dB/°C. They can handle an average input power of 200 mW and have a VSWR of less than 1.70:1. These TVAs are highly reliable passive solutions for over-temperature gain compensation. These rugged, MIL-PRF-55342 certified attenuators are available as a chip package and are suitable for use in power amplifiers, instrumentation, mobile networks, point-to-point radios, satellite communications, military radios, and up/down converters. They have an operating temperature range from -55 to +150 °C.
