The SAA1057 is a PLL synthesized FM transmitter circuit designed for radio frequency applications. The operation of the circuit is managed by a Microchip PIC16F84 microcontroller, which supports button inputs and controls a 2-line, 16-character LCD display.
The voltage-controlled oscillator (VCO) is implemented using transistor Q8, paired with two BB109 varactor diodes. A buffer transistor, Q7, separates the VHF signal into two paths, with one directed to transistor Q9. This configuration allows for precise frequency control and transmission.
The system utilizes the PIC16F84 microcontroller as its central processing unit. It handles user inputs from buttons and manages the output to the LCD display, providing operational feedback. The circuit is suitable for various FM transmission projects requiring synthesized frequency control.
