A wireless transceiver without trainable function to measure carrier frequency from a target remote control device is provided with multiple independent modulating transmitters to successively transmit two or more different output RF with different predetermined carrier frequency but modulating with same signal control code in turn for every time of operating remote control, which comprises a control key unit, a microcontroller unit (MCU), a memory unit, a code-copied unit and a modulating transmitter means with multiple independent modulating transmitters, and in use is capable of saving costs and being widely applicable to remotely control many remote-controlled appliances with same predetermined carrier frequency only by single piece of the invented wireless transceiver.
