A radiometer for a microwave receiver according to an embodiment of the present invention comprises: an antenna line through which radiation power corresponding to the temperature of a probe is received from an antenna; a first reference rod having a first reference temperature fixed in advance; a second reference rod having a second reference temperature fixed in advance; a first microwave switch for selectively switching the antenna line, the first reference load, and the second reference load; a second microwave switch switched with the same clock as the first microwave switch; a demodulator for multiplying a signal output from the second microwave switch by a predetermined gain value and outputting same; an integrator for integrating the signal output from the demodulator; and a controller for measuring the temperature of the probe on the basis of a signal output from the integrator.

Radiometer for microwave receiver and method for measuring temperature of probe thereof

Provided are a radio frequency (RF) receiver module for sensing core body temperature and an RF microwave core body thermometer system having the same. The RF receiver module for sensing core body temperature and the RF microwave core body thermometer having the same include: an RF contact-type patch antenna attached to a body part to sense the core body temperature; an RF receiver circuit unit attached to the body part to receive any one RF frequency signal within an RF frequency range of 1 to 10 GHz except for 1.4 GHz, 1.6 GHz, 1.7 GHz, 2.6 GHz and 2.7 GHz through the RF contact-type patch antenna for sensing core body temperature; and an interface circuit unit for connecting the RF receiver circuit unit to a control unit of a microprocessor control unit.
