The ALD-Ka-1001 from AtlanTecRF is a dual channel Test Loop Translator that can be used in a variety of test applications for frequency conversions from Ka-Band (Tx) to L-Band (Rx) and from L-Band (Tx) to Ka-Band (Rx). It down-converts an input Tx frequency from 27.5 to 31.50 GHz to an output Rx frequency from 950 to 1700 MHz and upconverts an input Tx frequency from 950 to 1700 MHz to an output Rx frequency from 17.70 to 21.20 GHz. It has a LO phase noise of -110 dBc/Hz at 1 MHz offset and non-signal related spurious are guaranteed at below -60 dBc at 27 GHz.
The architecture of each channel contains a synthesized local oscillator (LO), the frequency of which can be changed in either 25 MHz steps or 1 KHz steps so that the Tx and Rx bands relate to the L-band modem frequencies of 950-1700 MHz. The transfer characteristics of each path can also be defined independently in terms of attenuation range, conversion loss and filtering to suit the performance requirements of the individual station. Frequency stability is assured with a choice of either internal OCXO with better than +/-0.05ppm over temperature or by an external 10 MHz system source. The unit is available in 19-inch 2'U' high chassis, suitable for rack mounting, is 343 mm deep and may be fitted with rack slides.
