The XTSLIN-50X-B1 from Comtech Xicom Technology is a SATCOM Block Upconverter that converts an input IF frequency of 950-1450 MHz to an output RF frequency of 7.9-8.4 GHz. This GaN technology based BUC has an external LO reference frequency of 6950 MHz and an IF/Reference input impedance of 50 Ohms. It has a saturated output power of 100 W and has a minimum linear power of 50 W. The BUC has a small signal gain of 58 dB and a gain attenuation range of 25 dB in 0.1 dB steps. It has a noise power transmit/receive band value of -75 dBW/4 kHz and a maximum phase noise value of up to -103 dBc/Hz. The BUC has a harmonics value of -60 dBc and an output spurious of -60 dBc. It requires a DC supply of 22-56 V and has a linear power consumption of 300 VA. The BUC supports Ethernet, RS-232 and RS-485 interfaces for monitoring and control. It has a high efficiency GaN technology module that weighs 4.6 Kg and measures 11.16 x 5.4 x 4.43 inches.
