G.T. Microwave Features:

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

TTL Compatible Logic:
Logic ‘1’ /BIT = Value of Attenuation and all Logic ‘0’ = Insertion Loss. Attenuators without TTL driver; +1VDC @ +60mA = Value set and all =1VDC @ -60mA = Insertion Loss. For options, consult factory.

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

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

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

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

Standard Interfaces: RF port connectors are ‘SMA’, female per MIL – C – 39012. DC/LOGIC connections are solder terminals. Call factory for optional connectors.

Matched phase & Amplitude: Models listed are available matched unit to unit.
