Abstract

Disclosed is a multi-channel beam scanning receiver that can reduce area and manufacturing cost by implementing the beam scanning receiver including multi-channel antennas on one substrate. A multi-channel beam scanning receiver according to an exemplary embodiment of the present disclosure includes: a multi-channel antenna; a switch configured to select one of a plurality of signals received through the multi-channel antenna; and a first low-noise amplifier configured to The signal selected in the switch undergoes primary amplification; a bandpass filter configured to filter the primary amplified signal; a second low-noise amplifier configured to secondary amplify the filtered signal; and a detector, Configured to convert the secondary amplified signal into a voltage.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from Korean Patent Application No. 10-2011-0139142 filed with the Korean Intellectual Property Office on December 21, 2011, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to a beamscan receiver for a passive radiometer. Background technique [0004] A beam scanning receiver for a passive radiometer according to the prior art receives a signal by using a single antenna, amplifies the received signal in a low noise amplifier (LNA), and then amplifies the amplified signal by using a signal mixer After the signal is converted to an intermediate frequency signal. Next, the beam scanning receiver uses a scheme of converting the converted signal into a voltage in a diode detector through an impedance matching circuit, amplifying the converted voltage in a DC amplifier, and then outputting the...
