20 dB I & Q Vector ModulatorsFunctioning 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: Standard models include temperature compensation in a range from 0° to +50° C. 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.
