Abstract: A multiple tuner arrangement is formed on a single integrated circuit having a common radio frequency input terminal. The terminal supplies a broadband input signal to a plurality of individual tuners, which may be identical to each other in construction. The tuners operate simultaneously and independently of each other to convert a channel in the radio frequency input to the appropriate output intermediate frequency and supply this to the channel output terminal. Features such as a databus interface and a common reference oscillator for channel frequency synthesisers need not therefore be duplicated.
