>Microwave Journal
>
>
>The Thermopad(r) temperature variable attenuator (TVA) has gained
>widespread popularity among RF and microwave circuit designers as a
>simple solution to compensate gain variation over temperature. The TVA
>is a special case of the absorptive attenuator wherein the attenuation
>characteristic varies in a prescribed manner in response to the device
>temperature, all the while maintaining substantially constant
>characteristic impedance. TVAs find application in gain stages, mixers,
>local oscillators and other signal processing components to stabilize
>gain over temperature.
>
>System applications include anything from satellites to broadcast
>transmitters to cell towers. The TVA can replace closed- or open-loop
>temperature compensation schemes with a single, passive device requiring
>no external sensor, bias or control. Since it is a passive, low power,
>resistive device, the TVA produces no distortion products and can
>increase system reliability and reduce total system cost. EMC introduced
>the temperature variable attenuator in 1992 (US Patent No. 5,332,981)
>with the TVA product line (DC to 6 GHz), and has since expanded the
>product offerings to include the CTVA (75 W), the MTVA (DC to 12.4 or 18
>GHz) and HTVA (DC to 20 GHz). The new KTVA further expands the Thermopad
>product line with wideband performance in the 18 to 42 GHz frequency
>bands.
