Receiver including linearity compensation in the receive band
The receiver has a band pass filter (6) allowing passage of signals with intermediate frequency band, and performing impedance matching with a coaxial cable (5). An integrated tuner (7) including a low noise amplifier (70) is connected to the filter. A compensation circuit (8) placed between the tun...

| Zusammenfassung: | The receiver has a band pass filter (6) allowing passage of signals with intermediate frequency band, and performing impedance matching with a coaxial cable (5). An integrated tuner (7) including a low noise amplifier (70) is connected to the filter. A compensation circuit (8) placed between the tuner and the filter has transfer characteristics inverse to that of the amplifier in the intermediate frequency band. The circuit comprises a series arrangement of a resistor (80), microstrip inductor (81) and a capacitor (82). |
