It compensates cable losses between the antenna and the car radio, which is usually placed far away from the antenna. The device can be used in the frequency range of 50 up to 900MHz i.e. FM, DAB + , DMB, DVB-T, ISDB-T, etc. and has the flexibility to address different antenna types e.g., glass, windscreen, roof antennas . A separate automatic gain control AGC function is integrated in order to avoid overdriving the RF amplifier at large signal conditions. The integrated PIN diode drivers help to reduce the external component cost and to minimize the board space. The external component cost can be further reduced as the voltage regulation stage is also integrated. This stage provides overvoltage protection and current limitation. An external transistor is used as power driver for this stage.
