Variable transmission output for fill state measurement

摘要

The electronics module (100) has signal source (101) for generating a transmitting signal with frequency of more than 20 GHz, and high-frequency amplifier (102) for amplifying the transmission power of transmitting signal. A signal switch (103) switches the transmitting signal generated by source from amplified transmission power to lower transmission power, by bypassing the high-frequency amplifier or by switching OFF the drain voltage. Independent claims are included for the following: (1) fill level radar; (2) method for varying transmission power of transmitting signal and for measuring fill level; and (3) computer readable medium storing program for varying transmission power of transmitting signal and for measuring fill level.
