The TLT642 from Peak Communications is a Test Loop Translator with an input frequency range of 6.425-6.725 GHz and an output frequency range of 3.4-3.7 GHz. This test loop translator has an LO frequency of 10 MHz and an impedance of 50 Ohms. It has an input return loss of 18 dB and an output return loss of 15 dB. The test loop translator has a maximum input power of 15 dBm and a phase noise of up to -125 dBc/Hz. It has a conversion loss of 20 dB and a gain stability of +/- 0.25 dB. The test loop translator requires an input supply voltage of 90-264 VAC and has a power consumption of 30 W. It features full alarm monitoring and an optional 0-30 dB variable attenuator control. This rack mount test loop translator has a mass of 4.5 Kg and measures 1.75 x 19 x 21 inches (H x W x D). It is designed for translating a C-band transmit signal to the C-band receive signal which can then applied to the receive equipment in a test mode.
