KTVA Series Temperature Variable Attenuators

Smiths Interconnect|EMC's KTVA high frequency Thermopads are ideal for millimeter-wave amplifiers. KTVA is capable of handling 100mw input power and available in wire bondable and surface mount packages. The recently released K2TVA handles 200mw input power and provides highest shift over temperature from 27 GHz to 32 GHz. It is offered in 3, 4, 5 and 6dB with TCA shifts of -0.005 and -0.007dB/dB/ºC.

Standard narrowband versions cover specific segments in the K and Ka bands. An optimized broadband version operating from 16 to 36 GHz is also available.

The KTVA chip attenuator is available in designs of 3, 4 and 6 dB and temperature of attenuation coefficients (TCA) values of .003, .004, .005, and .006 dB/dB/deg C with an operating temperature from -55 to +150 ºC. The KTVA design also offers custom frequency band responses for narrow band applications with improved VSWR performance and attenuation accuracy. This product is space qualified and has flight history for those requiring pre-qualified space flight heritage.
