The TRR-2B-2 from GeoSync Microwave is a Test Loop Translator with an input frequency range of 27.5-30.0 GHz and an output frequency range of 17.7-19.6 GHz. This test loop translator has an LO frequency of 9.8/10.4 GHz and an impedance of 50 Ohms. It has an input/output return loss of 18 dB and a level control of 50 dB. The test loop translator has a noise figure of 30 dB at minimum attenuation and an intermodulation of -50 dBc. It has a minimum non-signal or LO-related spurious of -60 dBc and phase noise of up to -100 dBc/Hz. The test loop translator supports RS422 or RS485 serial interface and 10/100 Base-T Ethernet interface. It requires an input supply voltage of 90-250 VAC and has a power consumption of 40 W. The test loop translator weighs 4.5-6.4 Kg and measures 19 x 1.75 (panel height) x 20 inches. It is designed for satellite communication applications where frequency translation is needed with a minimum amplitude and group delay distortion.
