High-frequency power amplifier circuit
The combination with the receiver IC TA7657P is optimal.
27 MHz and 40 MHz transmission systems on a single chip
You can do this, and you will get four different control modes.
The modulation frequency can be set arbitrarily.
Wide operating supply voltage range.
: Yopr=6~10V, Recommended Voc=9V
Fewer external parts are required.
