Voltage Controlled Attenuators

Offering options that include linearized control slope, narrowband optimized performance, temperature compensation, video filtering and sub-assembly integration.  Operating frequency ranges span from 250 MHz to 40 GHz in up to 9:1 bandwidths.

 

Frequency Ranges:  From 250 MHz to 40 GHz, any optimized bandwidth is available.

 

Voltage Controlled:  0 Volts = Insertion Loss (zero attenuation) to +10 Volts = Maximum Attenuation.  Linearized models available upon request.

 

High Speed Switching:  Attenuators listed are measured from any set value to any value.  Switching speeds up to 300 ƞSec on request.

 

Low DC Power Consumption:  Attenuators require ±15 VDC, ±1% @ ±50 mA.

 

Stable Attenuation:  Variation vs. temperature from -55° to +85° C is typically ±10% of the set value. 

 

Operating Temperature Range:  Standard models include temperature compensation in a range from 0° to +50° C.  For more severe environments, please consult the factory.

 

Standard Interfaces:  RF port connectors are ‘SMA’ female per MIL-C-39012.  Control connections are solder terminals.  Please consult the factory for additional options.
