The KFA Series from Smiths Interconnect comprises 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. They 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%.
These small-signal attenuators are available as either wire-bondable or surface-mount devices (tape-and-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.
