This application note explains about an Auto Gain Control (AGC) for FM Radio Frequency using ON Semiconductor's NSVP264SDSF3, NSVR351SDSA3 and NCV2904.
- NSVP264SDSF3 is a dual type PIN diode best suited for high-frequency applications which is assembled in the 3-pin surface mount package.
- NSVR351SDSA3 is a dual type silicon schottky barrier diode best suited for high-frequency applications which is assembled in the 3-pin surface mount package.
- NCV2904 is a Single Supply Dual Operational Amplifiers which is assembled in the 8-pin surface mount package.
The evaluation board is adjusted to achieve the most suitable performance on FM Radio Frequency (90 MHz). A standard material FR4 is used for the printed circuit board (PCB). Please note that the losses of the PCB and the SMA connector are not excluded from the Power level.
