Voltage Controlled AttenuatorsOffering 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.
