摘要：
An input circuit for an HF-transmitting component 1 of a battery-operated device for the transmission of a data signal aims to reduce the power consumption. For that purpose the fundamental frequency of a reference oscillator 5 is modulated with the digital data signal, the data rate being greater than 20 kchip/s. For smoothing of the modulated reference signal an amplitude limiter 11 and a band pass filter 15 are connected between the reference oscillator 5 and the HF-transmitting component 1.
