The STA-60-12-D8 from Sage Millimeter is an E-band direct reading, rotary vane attenuator that operates from 60 to 90 GHz. The attenuator has a large scale calibrated dial which indicates the attenuation value directly. It has an attenuation range of up to 70 dB, an insertion loss of 1 dB and can handle an input power of up to 100 mW. The accuracy of the attenuator is 0.1 dB or 1% of the reading up to 60 dB, and "for reference only" above 70 dB. The attenuator is an ideal piece of equipment in waveguide systems where a broad direct reading of attenuation is required. It has a WR-12 Waveguide with UG-387/U Flange at the RF port and is ideal for the test lab, bit error rate testing, fade margin and transceiver diversity applications.
