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.
