GeoSync Microwave Introduces New S-Band Converters

GeoSync Microwave has introduced a new series of S-band Dual Conversion Synthesized Frequency Converters that cover the standard RF band of 2.0 to 2.4 GHz with an IF frequency of 70 MHz or a 140 MHz option.

Standard model converters can be tuned over the band in 1 kHz steps.  Custom step sizes as small as 0.1 Hz over narrower bands of interest are available as an option. The converters use GeoSync’s proprietary frequency synthesizer designs as the LOs which permits flexibility in meeting special band requirements.  Typical phase noise over the full band is -90 dBc/Hz at 1 kHz offset.  Custom models covering narrower band easily achieve -100 dBc/Hz at a 1 kHz offset.  If required, alternative IF frequencies to the standard IF frequencies of 70 or 140 MHz can be provided.

The upconverter gain of 32 dB typical is adjustable over 30 dB in 0.2 dB steps.  Also, the nominal downconverter gain of 46 dB is adjustable over a 30 dB range in 0.2 dB steps.  Control is via 10/100Base-T Ethernet or serial RS422/RS485.  Complete specifications can be found in GeoSync’s GS-1SPC data sheet.  The upconverter model number is UTR-200240 and the downconverter model number is DTR-200240.
