G.T Microwave Features:

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

TTL Compatible Logic: 2 BIT Binary Logic:

E1 E2 OUTPUT
0 0 0° REF
1 0 +270°
1 1 +180°
0 1 +90°

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

DC Power Consumption: : ±5 V @ ±100mA.

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.
