Abstract
Disclosed is a technology related to a low noise amplifier applied between an RF receiver and an RF switch. A phase difference matching circuit having the same phase difference as a positive gain amplifier is added to an output terminal of an attenuator of a low noise amplifier having a variable gain switching structure. In addition, a variable impedance circuit connected to an output terminal of the positive gain amplifier and an output terminal of a phase difference matching unit to finely adjust the phase difference of each output terminal may be further included.
