摘要： A high-frequency circuit board capable of easily forming a bias line whose resonance frequency is sufficiently separated from operating frequency is provided. On a high-frequency circuit board 100, by electrically connecting a bias line 11 to a high-frequency circuit 10 using blind via holes 106 and 107, it is possible to limit the route that has a possibility of producing resonance only to the bias line connecting the ends 106a and 107a of the blind via holes 106 and 107 to the bias line 11. By adjusting the route length from the end 106a to the end 107a, it is possible to prevent production of resonance in the vicinity of the operating frequency.

摘要： There is provided an in-vehicle pulse radar that permits to detect information on an object accurately by temporally separating a noise signal mixed into a receiving signal by applying a delay time with a simple configuration. A baseband signal down-converted by a frequency converter (152) is output to a signal processing section (102) through a board-to-board connector (103) after passing through a delay circuit (153). Still further, a control signal is output to a switching circuit (151) from a control signal generating section (162) through the board-to-board connector (103). The delay circuit (153) increases a time lag from when the control signal passes through the board-to-board connector (103) until when the baseband signal passes through the board-to-board connector (103) by applying a predetermined delay time to the baseband signal. Thereby, the baseband signal receives no interference from the control signal.

摘要： Provided is a quadrature demodulator capable of appropriately correct an amplitude error and a quadrature error even with respect to a pulse-modulated signal. In the quadrature demodulator 100, in order to compensate an amplitude error and a quadrature error, the phase adjuster 112 is provided in the local oscillation unit 110, and the quadrature detection error detector 131 and the quadrature detection error compensator 132 are provided in the signal processing unit 130. The quadrature detection unit 120 outputs two sets of I and Q-components of an RF signal using two LO signals that have been phase-shifted by the phase adjuster 112. In the quadrature detection error detector 131, an amplitude error and a quadrature error are calculated using the two sets of I and Q-components. The quadrature detection error compensator 132 compensates a received signal using the amplitude error and the quadrature error.
