IPC: H04N5/44
Filed: 2000-11-14
Abstract: PROBLEM TO BE SOLVED: To provide a tuner for receiving a digital signal, which can unnecessitate tracking adjustment and also minimizes noise. SOLUTION: A received signal is inputted to input switching circuits 2, 14 and 22 after passing through an HPF1 and switched to the respective circuits of a high band, a mid band and a low band. The received signals of the respective bands are subjected to band switching by high frequency amplifier input BPFs 30, 150 and 230. High frequency amplifiers 4, 16 and 24 amplify a high frequency, high frequency amplified output BPFs 50, 170 and 250 subsequently derive the received signals, mixer circuits 6, 18 and 26 mix the receives signals with local oscillator signals from local oscillator circuits, 7, 13 and 8, and an intermediate frequency signal is derived to an IF amplifier circuit 19, a SAW filter 20 and an IF amplifier circuit 21.
