radio control transmission

Square wave generator

Variable duty circuit

Carrier oscillator circuit

Mixer circuit

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.
