Patent number: 10228469Abstract: The present technology relates to a reception device that can realize low power consumption. The reception device comprises an RF unit, a demodulating unit, and a control unit. The RF unit includes a filtering unit, an amplifying unit, and an A/D converter. The filtering unit allows an IF signal to pass within a predetermined band. The IF signal is acquired by mixing a reception signal received from a positioning satellite with a local oscillation signal generated by a local oscillation unit to perform frequency conversion of the reception signal into an intermediate frequency. The amplifying unit amplifies the IF signal with a predetermined amplification factor. The A/D converter converts the IF signal from an analog signal into a digital signal. The demodulating unit demodulates the digital signal. Based on the demodulation, the control unit controls an operation of the RF unit. The present technology is applicable to a GNSS receiver.Type: GrantFiled: February 13, 2015Date of Patent: March 12, 2019Assignee: SONY SEMICONDUCTOR SOLUTIONS CORPORATIONInventors: Hitoshi Tomiyama, Suguru Houchi, Katsuyuki Tanaka, Hideki Yokoshima, Yuya Kondo
