G.T Microwave Features: IQ Vector Modulators

The function of an IQ Vector Modulator is to simultaneously control the phase and amplitude characteristics in the processing of a microwave signal. This Vector Modulator Device will convert a signal to a desired vector location via a digital command.

Frequency Ranges: From 500 MHz to 22 GHz up to 9:1 bandwidths are available.

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.

Digital or Voltage Control: I & Q Vector modulators simultaneously control attenuation (dB) and phase shift (Ø) by finding their 1 = 10 – (dB /20) cos Ø & Q = 10 sin Ø on the chart below and chart below and submitting the results to the POWER /I & Q LOGIC connector.

Low DC Power Consumption: I&Q Vector Modulators require +/-12 to +/-15VDC @ +/-100mA.

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.
