摘要： A wireless receiver includes an RSSI generation circuit that obtains RSSI output corresponding to a carrier strength level of a received RF signal; a lookup table from which a threshold value corresponding to temperature information from a temperature sensor is read based on the temperature information; a comparison circuit that generates comparison output when the RSSI output is below the threshold value read from the lookup table, in which the threshold value is one input, and the RSSI output from the RSSI generation circuit is the other input; and a muting circuit that closes a signal line of an audio signal demodulated from the RF signal, and cuts off output of the audio signal, based on the comparison output from the comparison circuit. The above configuration enables the wireless receiver to eliminate fluctuation of a reception reaching distance relative to temperature change, and ensure stable mute operation.

摘要： A gain temperature compensation circuit producing a relatively small loss of power, and enabling modification of a variation width of the attenuation amount in a predetermined temperature range is provided. A gain temperature compensation circuit includes a circulator and a thermistor. The circulator outputs a signal being input to a first port to a second port, and outputs the signal being input to the second port to a third port. The thermistor being connected to the second port reflects the signal being output from the second port by varying the power of the signal according to temperature, so as to input to the second port, in order to adjust the attenuation amount of the signal.

摘要： A gain compensation circuit comprises a first amplifier, a second amplifier, a filter, a first attenuator, a second attenuator and a third attenuator. The first amplifier is configured to amplify an input signal of the microwave signal processor. The filter is disposed between the first and second amplifiers. The first attenuator is disposed between the first amplifier and the filter for reducing return loss of the microwave signal processor. The second attenuator is disposed between the second amplifier and the filter for reducing return loss of the microwave signal processor. The third attenuator is electrically connected to the output of the second amplifier for reducing noise figure of the microwave signal processor and providing first and second gain compensations. The first gain compensation keeps the gain of the microwave signal processor constant under various temperatures, and the second gain compensation adjusts a nominal gain of the microwave signal processor.

摘要： A thermistor drive circuit includes a plurality of driving resistors, at least one current correction resistor, a voltage measurement unit and a controller. The driving resistors are selectively connected to a thermistor for correcting a temperature characteristic of the thermistor whose resistance value changes in accordance with a temperature to be detected. The current correction resistor is selectively connected between a power supply and a ground. The voltage measurement unit measures a terminal voltage of the thermistor. The controller switches connection states of the driving resistors according to the terminal voltage. When switching the connection states of the driving resistors, the controller also switches a connection state of the current correction resistor to suppress a fluctuation of a power supply current before and after the switching of the connection states of the driving resistors.
