The TRR-29.75-19.95 from GeoSync Microwave is a Test Loop Translator with an input frequency range of 29.5-30 GHz and an output frequency range of 19.7-20.2 GHz. It has an LO frequency of 9.8 GHz and an impedance of 50 Ohms. This test loop translator has an attenuation adjustment range of 30 dB and an amplitude response of ±0.25 dB. It has an input/output return loss of 18 dB and a conversion loss of 15-25 dB. The test loop translator has a noise figure of 15-25 dB and a phase noise of up to -120 dBc/Hz. It supports an RS-485 or RS-422 serial interface and a 10/100 Base-T ethernet interface. The test loop translator requires an input supply voltage of 90-250 VAC and has a power consumption of 40 W. It has a mass of 4.5-6.4 Kg and measures 19 x 1.75 x 20 inches. The test loop translator is designed for satellite communication applications where frequency translation is needed with a minimum amplitude and group delay distortion.
