Front-end integrated circuit for television receivers

A television tuner system comprising:

• a tuner front-end circuit having
• a first filter block that receives an RF signal, terminates the RF signal for one or more unwanted frequency bands, and outputs an unterminated signal;
• a second filter block that receives the unterminated signal, provides selectivity by filtering the unterminated signal into a plurality of separate signals, each of the plurality of separate signals being of a different desired frequency band, and outputs the plurality of separate signals;
• and
• an amplifier block that amplifies each of the plurality of separate signals and outputs each amplified separate signal,
• wherein the second filter block includes a signal bypass configured to receive the unterminated signal from the first block and output the received unterminated signal to the amplifier block such that the received unterminated signal bypasses the filtering of the second filter block;
• and
• a tuner capable of receiving one or more of the amplified separate signals.

A method of processing a radio frequency (RF) signal, comprising:

• receiving the RF signal;
• terminating the RF signal for unwanted frequency bands to produce an unterminated signal;
• separating the unterminated signal into a plurality of separate signals of differing desired frequency bands to provide selectivity, including bypassing the separating for an equivalent version of the unterminated signal to produce an separated signal;
• amplifying each of the plurality of separate signals and the unseparated signal;
• and
• outputting the amplified separate signals and the amplified unseparated signal.
