60 dB I & Q Vector Modulators

Functioning to simultaneously control the phase and amplitude characteristics in the processing of a microwave signal from 200 MHz to 22 GHz in up to 9:1 bandwidths.  Narrowband models available from 22.0 GHz to 35.0 GHz with 10% bandwidth.  Model offerings include digital or voltage controlled, low phase noise options, 500 ƞSec or 1.0 µSec switching speeds, and high dynamic range capabilities.

 

 Description:  The function of an I & Q 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 200 MHz to 22 GHz, up to 9:1 bandwidths available as well as any optimization.  Narrowband models available from 22.0 GHz to 35.0 GHz with 10% bandwidth.

 

Operating Temperature Range:  The 500 ƞSec models have an optional expanded operating temperature range from -55° to +85° C with a temperature coefficient of (±0.03 dB & ±0.10°)/° C.  The 1.0 µSec 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, please consult the factory.

 

High Speed Switching:  I & Q Vector Modulators listed are measured from any set value to any set value. 

 

Digital or Voltage Controlled:  I & Q Vector Modulators simultaneously control attenuation (dB) and phase shift (ø) by finding their I = 10 – (dB/20) cos ø & Q = 10 sin ø on the chart below and submitting the results to the Power/I & Q Logic connector.

 

 

 

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

 

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

 

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

 

Standard Interfaces:  RF port connectors are ‘SMA’ female per MIL-C-39012.  Please consult the factory for additional options.

 

Life Time Integrity:  I & Q Vector Modulators can be designed to meet MIL-E-16400, Range 1 and MIL-E-5400, Class 2 environments operating within the -55° to +85° temperature range.

 

Low Phase Noise Option:  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.  Please specify when ordering.
