Radio Frequency Translator Plate
Photo of wideband radio frequency translator plate. Developed at the SMA project office by Derek Kubo and John Kuroda for the AMiBA digital correlator upgrade, this prototype plate provides signal conditioning and frequency translation of a pair of 3.6-5.6 GHz intermediate frequency channels to baseband for digitization. Two of these plates are currently deployed at the Mauna Loa facility to support testing of the new digital correlator.
This frequency translator plate (dimensions 33.0 x 16.5 x 1.5 cm) was developed specifically to observe the 87.6-89.6 GHz portion of the sky for the detection of HCN and HCO+ in Orion. A more versatile version of this frequency translator based on an I/Q conversion technique has been developed and is currently in test with the digital correlator in Taipei. Should this effort be successful, it will permit operation of the digital correlator to operate over any user selectable 4 GHz portion of the 86-102 GHz receiver band.
