Noise occurs naturally in any active device or circuit limiting the minimum levels of useful signals causing unwanted interference on weaker signals. Therefore, it is important to design circuits to minimize the effects of noise by quantifying them in the form of noise parameters. The MT7553 series enhances the typical noise system measurement accuracy reducing the total system noise figure by adding an integrated switch and wideband LNA close to the DUT. The Noise Switching Module integrates the entire input network while the Noise Receiver Module integrates the entire output network of a typical noise parameter measurement system into a turnkey solution.
