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 degree
Resolution (L.S.B.) or all Logic '0' = 0 degrees Reference
state. Up to 12 BIT resolution available upon request.
Optional Models: Analog Voltage controlled
models. Dual function models, selectable input for either
translator or phase shifter operations.
High Speed Switching: Frequency Translators
listed are measured from any set value to any value.
Translation Rate: From 0 to 500 kHz
the Carrier Suppression is 25 dB and Sideband Suppression
is 20 dB Minimum.
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.
Low DC power Consumption: Frequency
Translators require +/-12 to +/-15 VDC @ +/-100 mA.
Stable Phase Shifts: Variation vs Temperature
is typically +/-0.17 degrees & +/-0.035 dB/degrees
C from -10 to +65 degrees C for 500nSec 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
Frequency Translators
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.
