G.T. Microwave Features:

Frequency Ranges: From 500 MHz to 24 GHz up to 9:1 bandwidths are available.

TTL Compatible Logic: G.T.M.I’s binary logic Digital to Analog Converter with 8 inputs;
Logic ‘1’ / BIT = 256 discrete phase shifts with a 1.4’ Resolution (L.S.B) or all Logic ‘O’ = O’ Reference State. Any resolution up to 12 BITs is available.

Optional Models: Analog Voltage controlled or Switched Line Digital phase shifters are available, please consult factory.

Operating Temperature Range: 500 nSec models have an operating temperature range from -55°C to +85°C with a temperature coefficient of (+/- 0.03 dB & +/- 0.10°)/°C. 1.0 uSec models are better for temperature stability. Insertion phase drift is (0.03° x frequency)/°C or 0.1° Min to 0.54° at 18 GHz. For severe environments, consult factory.

High Speed Switching: Phase Shifters listed are measured from any set value to any value.

Low DC power Consumption: Phase Shifters require +/-12 to +/-15VDC@ +/-100mA.

Stable Phase Shifts: Variation vs. Temperature is typically +/- 0.17 degrees & +/- 0.035 dB/degrees C from –10 to +65 degrees C for 500 nSec models. Slower models have better temperature coefficients, please consult factory.

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.

Life Time Integrity: G.T.M.I.’s Phase Shifters can be designed to meet MIL–E–16400, Range 1 and MIL – E – 5400, Class 2 environments operating within the -55° to +85° C temperature range.

Low Phase Noise Option: Specify when ordering, low phase noise option which offers a typical performance of
-132 dBc/Hz @ 10 kHz and -142 dBc/Hz @ 100 kHz offsets. Requires +/-5 VDC (<2%) @ +/-100 mA low noise regulated supplies and user supplied latch command for inputs.
