Narda Attenuator 777C 3 dB

Condition: Used

The Narda 777C-3 is a 3 dB fixed coaxial attenuator from Narda-MITEQ, covering DC to 12.4 GHz with Type N male-to-female connectors and a 2 W average power rating. A robust, precision-built passive RF component suited to laboratory and system integration use.

Supplied as pictured.

The Narda-MITEQ 777C series are fixed coaxial attenuators designed for precision RF and microwave applications from DC to 12.4 GHz. Manufactured using thin-film deposition techniques with stainless steel Type N connectors, the 777C series is bi-directional and available in standard attenuation values from 3 to 60 dB. The 777C-3 is calibrated at DC, 4, 8, 10, and 12.4 GHz, with attenuation certification recorded to the nearest 0.05 dB. All standard-line units feature stainless steel connectors for extended connector life and maintained VSWR performance. The series meets MIL-A-3933E environmental requirements.
