Ka-Band Digital Direct Reading Attenuator

STA-60-28-D5 is a direct reading, rotary vane attenuator for use in millimeter wave systems across the standard Ka-band frequency range of 26.5 to 40 GHz. The attenuator has a digital screen 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 0.8 dB maximum insertion loss and up to maximum 60 dB attenuation. The accuracy of the attenuator is 0.1 dB or 2% of the setting, whichever is larger, up to 40 dB, 3% up to 50 dB, and “for reference only” above 50 dB. The attenuator is powered by a rechargeable built-in battery, which can support up to 10 hours continues operation with the back light “on” and 40 hours with the back light “off”. The battery can be charged by a provided AC adapter via a standard USB C cable or the attenuator can be operated while charging by using the AC adapter.
