|Attenuators / Loads|
The Aspen Electronics range of fixed / variable attenuators and loads is truly comprehensive. Covering the frequency range from DC to 60GHz and power ratings from 2W to 2kW, in coax and waveguide we are confident that we have what you need no matter what the application.
A range of coaxial loads & attenuators including fixed, variable and step attenuators for production or test applications up to 18GHz. ATM's range of waveguide terminations are available in 5 different power ratings with models up to WR22 (50GHz), aswell as double ridge designs.
Aspen Electronics Ltd, as Bird's only approved European stockist has available for same day delivery a wide range of Attenuators with power ratings from 2W to 2kW, plus Loads/Terminations from 2W to 10kW.
The HVA series broadband PIN diode attenuators cover the waveguide bands from 18 ~ 110 GHz. The attenuators are available for applications requiring variations in power levels using a control voltage.
Produces a range of custom designed digital attenuators for military and commercial applications up to 3GHz.
Specialising in chip and flange mount resistive products, ResNet can supply both custom and industry standard products for all applications. In addition their range of coaxial attenuators & terminations provide a cost effective solution to any production requirement.

Aspen Can also supply:
- 1kW bi-directional 6dB attenuator for “wafer-fab” RF generator power control
- 5W, 130dB attenuator for radio system dynamic range testing
- 1200W, 40dB high accuracy attenuator for 470-860MHz Digital TV application
- 100W, weatherproofed attenuator with 7/16DIN connectors for outdoor RF systems
Lastly, something special. Do you operate a radio system and would like to attenuate the output of your radio but maintain the receiver sensitivity?
If so you might be interested in the Aspen “one way attenuator”. This was supplied to a customer who needed to reduce the output power of their telemetry radios whilst maintaining the full dynamic range of the receiver.
Because it was not possible to simply “turn down” the transmitter, as the radio was a sealed type approved system, the only option was to fit an attenuator to the duplexer output.
The Aspen “one way attenuator” provided 20dB in the transmit path, but only 0.4dB in the receive path. The result, one happy customer and the confirmation that “lateral thinking” does come in useful sometimes.
