Narda Microwave-East, an L-3 Communications company (Hauppauge, NY), has introduced the Model 769A family of bidirectional coaxial fixed attenuators for general-purpose and test and measurement applications. They operate from DC to 6 GHz, and are available with attenuation values of 3, 6, 10, 20, and 30 dB. All models handle a maximum input power of 150 W average and 3 kW peak, have a maximum VSWR of 1.35:1 or less, weigh 3.3 pounds, and have Type-N female connectors. Models with 3, 6, and 10 dB of attenuation have maximum attenuation deviation of ±0.4 dB to 2 GHz, and ±0.75 dB to 6 GHz. The 20 and 30 dB models have maximum attenuation deviation of ±0.5 dB to 2 GHz, and ±1 dB to 6 GHz.
