Continuously Variable
Flat with Frequency Types - Subminiature
Midwest Microwave's series of Subminiature 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
for designation information).

Midwest Microwave's series of Level Set Miniature Continuously Variable
Attenuators were designed to meet the most stringent environmental
conditions. The Level Set Types are useful for applications where a specific
level of attenuation is required at one frequency and flattness over the
frequency band is not 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).
