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.
