Rf downconverter-tuner

A RF downconverter-tuner system to convert one or more input signals into a lower range of frequency bands, comprising:

• one or more RF input ports for receiving said one or more input signals;
• one or more RF output ports for transmitting said output signal;
• a plurality of dual-mode switches coupled to two or more of the group consisting of said one or more RF input ports, said one or more RF output ports and one or more receive chains;
• said receive chain comprising:
• one or more mixers for converting said one or more input signals into said lower range of frequency bands;
• a plurality of filters for eliminating one or more of unwanted signal artifacts, band signals and spurious products;
• a bypass mode for allowing for one or more of said input signals that are outside of a frequency range of said RF downconverter-tuner system to pass through to said one or more RF output ports,
• a back-end receiver coupled to said one or more RF output ports such that a selection of said input signals are processed by said back-end receiver;
• an oscillator implemented with a frequency synthesis circuit;
• a plurality of amplifier stages for increasing the strength of said input signal and for compensating for losses due to said one or more mixers and said plurality of filters;
• one or more signal detection circuits for detecting the level of said input signals at various stages in said receive chain;
• and
• a plurality of controller ports for controlling said RF downconverter-tuner system.
