KFA Series Image

The KFA Series from Smiths Interconnect are Fixed Attenuators that operate from 16 to 36 GHz. They are available in attenuation values from 0 to 10 dB in 1 dB increments with an accuracy of ± 0.75 dB. These small signal attenuators can handle a CW input power of up to 200 mW and a peak input power of 2 W with a pulse width of 10 µs and a duty cycle of 1%. The attenuators are available as either wire bondable or surface mount devices (tape & reel or waffle package) and are constructed on an Alumina substrate with rugged thick film terminations and passivated Tantalum Nitride resistive elements. They also include a protective coating for added protection from various environmental conditions.

The KFA Series attenuators are suitable for satellite communications, instrumentation, amplifier circuits, transmit/receive modules, up/down converters, radar and broadcast applications.
