- IN STOCK - Please contact us if you need more units than what is available online.
Model STA-60-03-D1 is a direct reading, rotary vane attenuator for use in millimeter wave systems across the standard WR-03 waveguide frequency range of 220 to 325 GHz. The attenuator has a large scale dial which indicates the attenuation value directly. The attenuator is an ideal piece of equipment in waveguide systems where a broad direct reading of attenuation is required. The attenuator exhibits a typical 5.5 dB insertion loss and up to a maximum of 40 dB attenuation. The accuracy of the attenuator is 0.1 dB or 3% of the reading, whichever is larger, up to 40 dB. Readings above 40 dB are “for reference only”.
