G.T. Microwave Features:

Frequency Ranges: From 500 MHz to 24 GHz any optimized bandwidth is available.

TTL Compatible Logic: G.T.’s binary logic from 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.

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

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 can be matched unit to unit. Please consult factory.
