The TRR-6.1-3.9 from GeoSync Microwave is a Test Loop Translator with an input frequency range of 5.85-6.425 GHz and an output frequency range of 3.625-4.2 GHz. This test loop translator has an LO frequency of 2.225 GHz and an impedance of 50 Ohms. It has an input/output return loss of 18 dB and a maximum conversion loss of 25 dB. The test loop translator has a noise figure of 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 16 W. It has a mass of 4.5-6.4 Kg and measures 19 x 1.75 x 20 inches (chassis dimensions). The TRR-6.1-3.9 is ideal for applications requiring frequency translation with a minimum amplitude and group delay distortion.
