Digital Switched Pad Absorptive Attenuators Offering options from 1 to 8 bit TTL utlizing either solder pins or a multi-pin connector for control.  Options including narrowband optimized performance, video filtering and sub-assembly integration.  Operating frequency ranges span from 250 MHz to 20 GHz in up to 4:1 bandwidths.

Frequency Ranges:  From 250 MHz to 20 GHz, any optimized bandwidth is available.

TTL Compatible Logic:  Logic ‘1’ / BIT = Attenuation Value and all Logic ‘0’ = Insertion Loss.  Attenuator without TTL driver is +1 VDC @ 60 mA = Attenuation Value and all 1 VDC @ -60 mA = Insertion Loss.  For additional options, please consult the factory.

High Speed Switching:  Attenuators listed are measured from 50% TTL to 10% / 90% RF from any set value to any set value.  Faster switching speeds are available upon request.

Low DC Power Consumption:  Attenuators with TTL drivers require ±5 VDC @ +50 mA / BIT.

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

Stable Attenuation:  Variation vs. temperature listed is from -55° to +85° C.

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.  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.
