Narda Introduces Thumb-wheel RF Step Attenuator
Narda, an L-3 Communications company, introduced the model 743-60 step attenuator that provides attenuation of 0 to 60 dB in 10 dB steps via a thumb-wheel and direct readout, and covers DC to 18 GHz.
The model 743-60 is extremely precise, with attenuation deviation of +/-1 dB or less from 0 to 40 dB, and no more than +/-1.5 to 60 dB of attenuation. Resetability is less than 0.05 dB, VSWR is less than 1.5:1 and temperature stability is 0.0001 dB/dB/deg. C. The attenuator can handle RF input power of 2 W average and 200 W peak, and uses Type-N female connectors. The Model 743-60 measures 1.43" x 1.75" x 0.5" and can be panel mounted with an optional kit available from Narda.
