Patent ID: 8405542

Claim:
An electronics module for a fill level radar for varying a transmission output of a transmitting signal with a transmitting signal frequency above 20 GHz, the electronics module configured to measure a fill level, comprising: a source configured to generate the transmitting signal; a high-frequency amplifier configured to amplify the transmission power of the transmitting signal; and a first signal switch configured to switch the transmitting signal, after the transmitting signal has been generated by the source, from a first transmission power to a second transmission power, wherein the high-frequency amplifier is a monolithic microwave integrated circuit (MMIC), wherein the first signal switch is configured to switch on and off a drain voltage of the MMIC, wherein the electronics module is configured to reduce the transmission power from the first transmission power to the second transmission power by switching off the drain voltage of the high-frequency amplifier, and wherein the gate voltage remains switched on.
