摘要： An IC of a front end circuit which can be ready for various television broadcasting systems is provided. The front end circuit includes tuning circuits 12A to 12C and 14A to 14C and high frequency amplifiers 13A to 13C individually corresponding to a plurality of reception bands of television broadcasts. The front end circuit further includes a switch circuit 11 for selectively supplying reception signals to the tuning circuits 12A to 12C, and a switch circuit 15 for selectively extracting outputs of the tuning circuits 14A to 14C. The front end circuit further includes mixer circuits 21I and 21Q to which an output of the switch circuit 15 is supplied, and a PLL 30 for supplying local oscillation signals SLOI and SLOQ having phases orthogonal to each other to the mixer circuits 21I and 21Q. The front end circuit further includes a complex band-pass filter 24 to which outputs of the mixer circuits 21I and 21Q are supplied, and an output circuit 25 for mathematically operating an output of the complex band-pass filter 24 and outputting an intermediate frequency signal SIF.

摘要： Receiver architectures and associated methods are disclosed that provide initial analog coarse tuning of desired channels within a received signal spectrum, such as a set-top box signal spectrum for satellite communications. These architectures provide significant advantages over prior direct down-conversion (DDC) architectures and low intermediate-frequency (IF) architectures, particularly where two tuners are desired on the same integrated circuit. Rather than using a low-IF frequency or directly converting the desired channel frequency to DC, initial coarse tuning provided by analog coarse tuning circuitry allows for a conversion to a frequency range around DC. This coarse tuning circuitry can be implemented, for example, using a large-step local oscillator (LO) that provides a coarse tune analog mixing signal. Once mixed down, the desired channel may then be fine-tuned through digital processing, such as through the use of a wide-band analog-to-digital converter (ADC) or a narrow-band tunable bandpass ADC.
