| description | A tuner is provided for permitting independent reception of a plurality of channels from a multiple channel radio frequency input signal. A first analog converter of the upconverter type block-converts the radio frequency band to an intermediate frequency band. Several second analog frequency converters, such as quadrature ZIF downconverters, are independently controllable for independently selecting respective channels for reception from the intermediate frequency band at the output of the first converter. Each of the second converters converts the respective selected channel to the desired intermediate frequency. A voltage-driven interface is provided between the first converter and the second converters. |
