That says AM14/45, so it is surely BBC designed equipment. Not UHF so probably 88-108 MHz

I was once given a pair of SD1480 on a Band 2 PCB from someone who used to work at Eddystone radio, for use in a 144MHz PA.     I wasn't very successful at getting them going, but back in those days, the mid-to-late 1980s, hadn't got much in the way of test equipment.
