Narda, an L-3 Communications company, introduced the Model 752 family of precision fixed RF attenuators that includes models with 3, 6, 10, 20 and 30 dB attenuation and operate from DC to 3 GHz. They are an excellent choice for commercial as well as military applications, since they are designed to meet MIL-A-3933E environmental requirements.
All of the Model 752 precision attenuators have attenuation deviation of only +/-0.3 dB, maximum VSWR of 1.2:1, and handle 5 W average and 300 W peak RF input power. They weigh 3.7 oz. (105 g), and are ruggedly designed to take the rough handling to which these devices are often subjected. They have extremely low frequency sensitivity and minimum deviation in phase or group delay.
The Model 752 devices complement Narda’s other 700 Series attenuators, which include models with attenuation values up to 50 dB and cover frequencies as high as 18 GHz.
All versions of the Model 752 attenuators are available from Narda for immediate delivery.
