Abstract: A broadband integrated television receiver for receiving a standard antenna or cable input and outputting an analog composite video signal and composite audio signal is disclosed. The receiver employs an up-conversion mixer and a down-conversion mixer in series to produce an IF signal. An IF filter between the mixers performs coarse channel selection. The down-conversion mixer may be an image rejection mixer to provide additional filtering. The received RF television signals are converted to a standard 45.75 MHz IF signal for processing on-chip by additional circuitry.
