RECEIVER MODULE, MULTICHANNEL RECEIVER AND MRI DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide a receiver module capable of easily coping with an increase in the input signal number in the receiver module used for forming a plurality of input signals into one composite signal. PSOLUTION: An adder 1 for adding and outputting a first signal S1 inputted from an external part and an inside signal Q1 generated in an internal part as an output signal B1, a multiplier 2 for multiplying a second signal S2 inputted from the external part and an input reference signal Sr inputted from the external part, an amplifier 3 for outputting the inside signal Q1 by doubly amplifying amplitude of output of the multiplier 2, and a frequency divider 4 for outputting an output reference signal Sr-1 by dividing a frequency of the input reference signal Sr by 1/2, are formed as one module. The receiver module is joined in a plurality in series so that an output signal of the rear stage is set as the first signal of the front stage, and the output reference signal of the front stage is set as the input reference signal of the rear stage, to easily cope with an increase in the input signal number.
