Abstract

A level measuring instrument is provided, including a microwave integrated circuit in a form of a radar system on chip with at least two transmission hardware channels, each to generate a transmission signal, and at least two receiving hardware channels, each to receive reflected signals from a product surface; a noise level reduction device configured to increase a signal-to-noise ratio of a received signal, which relates to the reflected signals from the product surface, by averaging results of several measurements carried out in succession in time; or a signal level increasing device configured to combine, by an inverse Wilkinson divider, two of the transmission hardware channels to produce a combined transmission signal with increased power or to combine two of the receiving channels to produce a combined reception signal with increased power.
