Analysis of FM Transmitting Module C2

Recently, an FM transmission module C2 was mail-ordered from an electronics factory in Tianjin. This module is suitable for FM wireless transmission of audio signals. Each component is packaged in a 12mm × 22mm × 32mm plastic case. Because the module has the characteristics of simple interface and stable performance, it is decided to "dissect" the module once. See the attached circuit for the circuit drawn by physical measurement.
The working voltage of the module is 1 ~ 8 ~ 9V, the working current is 2 ~ 6mA, according to the component parameters obtained after the dissection, the working voltage of the module can be increased to 12V, so that the effective distance of the emission can be increased to 50 ~ 60 meters.
