PXV Series Thermo-variable Attenuators


Susumu's PXV series thermo-variable attenuators recommended for high-speed wireless communications


Susumu's thermo-variable attenuators decrease their attenuation as temperature increases, thus providing compensation for temperature sensitive amplifiers such as GaAs-type amplifiers whose output decreases with rising temperature. One PXV thermo-variable attenuator can replace a complex temperature compensating scheme involving an extra circuit. For example, a PXV attenuator eliminates the needs for an output feedback loop or a temperature sensing circuit. In order to meet varied customer needs, Susumu offers 90 different temperature compensating profiles.

The PXV series are highly recommended for the high-speed wireless communications because the PXV series has excellent high-frequency performance well into the GHz range. This is also where GaAs amplifiers excel and are commonly used.
