EMC Technology’s TVA Thermopad®s are microwave absorptive attenuators which provide power dissipation that varies with temperature and operate in frequency ranges from DC to 6 GHz. This surface mount, temperature variable attenuator requires no bias or control voltages and generates zero distortion. This product is available with various metallization styles and plating options including gold for wire bonding applications, RoHS compliant lead free silver over nickel plating, 60/40 low temperature solder plating or 60/40 solder fused finish for easy reflow processing. It is available in both negative...

Mini Thermopad® EMC Technology’s MTVA Thermopad®s are microwave absorptive attenuators which offer a smaller physical size with increased frequency range. The series operates DC to 18 GHz. The MTVA version of the Thermopad also offers wire bondable terminals for use with alternative high frequency attachment methods and space applications. This product is available with various metallization styles and plating options including RoHS compliant lead free silver over nickel plating, 60/40 low temperature solder plating or 60/40 solder fused finish for easy reflow processing MTVA Planar Series 1.9...

WTVA Double Wrap Wire Bond Series WTVA (20.0 GHz) Wide Band Thermopad® The WTVA is EMC’s wide band temperature variable attenuator. This product provides a good linear shift from DC to 20 GHz and from -55°C to +125°C. EMC Technology’s Thermopads® are microwave absorptive attenuators which provide power dissipation that varies with temperature. They are used to correct gain variations in amplifiers and other active components which tend to have gain anomalies over temperature. The WB2 style uses thick film gold wire bondable terminals. The SMTF style is a RoHS compliant surface mount configuration....

KTVA (36.0 GHz) EMC Technology’s KTVA high frequency Thermopads® are ideal for millimeter-wave amplifiers. KTVA is capable of handling 100 milliwatts input power and available in wire bondable and surface mount packages. Standard narrowband versions cover specific segments in K and Ka bands. An optimized broadband version operating from 16 to 36 GHz is also available. 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...
