Frequency Translators

Characteristics that affect the performance of frequency translators have been enhanced to include minimization of PM-to-AM conversion, use of high slew rate drivers and optimizing phase shift linearity with applied signal.  As a result, carrier and sideband suppression levels of over 25 and 20 dB are obtained across the entire frequency range, which ranges 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.

 

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.

 

TTL Compatible Logic:  Binary logic Digital-to-Analog converter with 8 inputs; Logic ‘1’ / BIT = 256 discrete phase shifts with a 1.41 degree resolution (LSB) or all Logic ‘0’ = 0° reference state.  Up to 12 BIT resolution available upon request.

 

Optional Models:  Analog Voltage Controlled models and Dual Function models available with selectable input for either translator or phase shifter operations.

 

High Speed Switching:  Frequency Translators listed are measured from any set value to any set value. 

 

Translation Rate:  From 0 to 500 kHz, the carrier suppression is 25 dB and sideband suppression is 20 dB minimum.

Low DC Power Consumption:  Frequency Translators 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.

 

Operating Temperature Range:  Standard models include temperature compensation in a range from -10° to +65° C.  For more severe environments, 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:  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° temperature range.

 

Low Phase Noise Option:  Offers a typical performance of -132 dBc/Hz @ 10 kHz offsets.  Requires ±5 VDC (<2%) @ ±100 mA low noise regulated supplies and user supplied latch command for inputs.  Please specify when ordering.
