摘要： An electromagnetic field measuring apparatus capable of measuring an electromagnetic field for a minuscule area in which electronic devices are densely packed with a high sensitivity is provided. In an electromagnetic field measuring apparatus according to the present invention, the amplitude level of signal light (pf) is adjusted by the analyzer (34) by adjusting its angle with respect to the plane of polarization of the signal light (pf) based on an amplitude level control signal (eb) supplied from the calculation control unit (40). An amplitude level control signal (eb) is supplied from the calculation control unit (40) to the analyzer (34) based on the spectrum (ea) of an electric signal (ed) measured by an RF spectrum analyzer (39). The amplitude level ration between the carrier and the sideband contained in the signal light (ph) incident on the optical receiver (38) is controlled to a fixed value.

摘要： In order that the total distance of a first high-frequency current path, which is defined in the periphery of slits (34a, 36a), satisfies a prescribed relationship, the slits (34a, 36a) are respectively formed in a first conductor pattern (34) and a second conductor pattern (36) that configure a coplanar line (30). Thus, the first high-frequency current that flows along the peripheries of the slits (34a, 36a) combines with a second high-frequency current that flows along a signal line conductor (32) without significantly affecting the second high-frequency current. Thus, radiated electromagnetic waves are efficiently collected, and radiation loss in a wiring substrate (10) is efficaciously alleviated.

摘要： In an optical transmitter which modulates a continuous-wave optical carrier with an electrical data pulse, the carrier is modulated with a clock signal having ½n (where n is an integer equal to or greater than unity) of the frequency of a fundamental sinusoidal component of the data pulse so that the modulated carrier contains at least a center frequency spectral component. On the modulated optical carrier a filtering operation is performed so that the filtered carrier contains a carrier frequency component and first sideband components. Before or after the clock modulation is performed, the data pulse is used to perform data modulation on the optical carrier.

摘要： A coplanar line formed on a high-frequency substrate of a high-frequency module includes a first dielectric layer, a signal line which is formed on the surface of the first dielectric layer and connected to a core line of a coaxial connector, a ground which is formed in opposite areas beside the signal line with a clearance therebetween, and a lower ground of the first dielectric layer. A second dielectric layer is laminated with the first dielectric layer so as to interpose the lower ground therebetween. Additionally, the lower ground is exposed on the terminal face of the high-frequency substrate coupled with the coaxial connector in either the first dielectric layer or the second dielectric layer and connected to an outer conductor of the coaxial connector. Thus, it is possible to prevent an insertion loss from increasing due to electromagnetic emission occurring in the clearance of the high-frequency substrate in response to transmitting signals in a high frequency range.
