G.T Microwave Features:

Frequency Ranges: From 100 MHz to 24 GHz any optimized bandwidth is available.

TTL Compatible Logic: Logic ‘1’ = Isolation and Logic ‘0’ = Insertion Loss. For switches without TTL driver, +1VDC @ +50mA = Isolation and -1VDC @ -50mA = Insertion Loss. For logic options, please consult factory.

High Speed Switching: Switches listed are measured from 50% TTL to 10% / 90% RF.

Low DC Power Consumption: Switches with TTL drivers require ± 5VDC @ 100/ -60mA.

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

Absorptive Switches: On these models the J2 – J4 ports are NON-REFLECTIVE.

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 with matched ports. Please consult factory.
