Digitally Controlled Phase Invariant 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 500 MHz to 18 GHz in up to 9:1 bandwidths.

Frequency Ranges:  From 500 MHz to 18 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.

High Speed Switching:  Attenuator listed is measured from 50% TTL to 10% / 90% RF from any set value to any 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.

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.  DC/Logic connections are solder terminals.  Please consult the factory for additional options.

Matched Phase & Amplitude:  Model listed can be matched unit-to-unit.  Please consult the factory.
