Digitally Controlled Attenuators

Offering options that include digital control with up to 4K of resolution, any desired control input slope characteristic, 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.

‍

TTL Compatible Logic: Binary logic Digital-to-Analog converter with 8 inputs: Logic ‘1’/BIT = 256 discrete values of attenuation or all Logic ‘0’ = Insertion Loss. Any resolution up to 12 BITs is available.

‍

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

‍

Low DC Power Consumption: Attenuators require ±15 VDC, ±1% @ +100/-50 mA.

‍

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

‍

Stable Attenuation: Variation vs. temperature from -55° to +85° C is typically ±10% of the set value. Temperature compensated models are ±2%.

‍

High RF Power Handling: For power levels greater than listed, please consult the factory.

‍

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