Midwest Microwave's series of Miniature Continuously Variable Attenuators
were designed to meet the most stringent environmental conditions. The Flat
with Frequency Types are useful for applications where a specific level of
attenuation is required over a frequency band and reasonable attenuation
flattness over the frequency band is necessary. The units are available in a
Standard simple locking type configuration, a Panel mount type with a knob,
or a Turns-counting dial type, also panel mounted, for refrence setting or if
calibration is desired. SMA connector configurations are standard, however
Type N or TNC connector configurations are also available (see note below).
