Abstract: An oscillator includes phase frequency detectors, each detecting the phase difference between two input signals (output signal and external reference signal) and outputting a control command signal for controlling the output signal to achieve a desired frequency on the basis of the phase difference. A plurality of ICs, each including a phase frequency detector, frequency dividers, a charge pump, and a lock detection circuit, is operated in parallel. A composite control command signal generated by combining outputs of the phase frequency detectors is output via a loop filter to a voltage-controlled oscillator. Whether phase noise is reduced sufficiently is determined on the basis of detection results by an amplitude detection circuit for detecting the amplitude of an AC component of the composite control command signal and the lock detection circuits. The phase frequency detectors are repeatedly reactivated until the phase noise is reduced sufficiently.

Abstract: A method for manufacturing a porous dielectric substrate including patterned electrodes includes a patterned electrode-forming step of preparing a support plate having a releasable flat face and then forming the patterned electrodes on the flat face, a porous dielectric substrate-forming step of feeding a material for forming the porous dielectric substrate onto the flat face having the patterned electrodes arranged thereon to form the porous dielectric substrate in which the patterned electrodes are embedded, and a separation step of separating the support plate from the porous dielectric substrate having the patterned electrodes embedded therein. In the patterned electrode-forming step, the patterned electrodes formed on the flat face are processed to have rough surfaces in the patterned electrode-forming step. Alternatively, after the flat face is coated with a releasing agent, the patterned electrodes are formed on the resulting flat face.

Abstract: In a frequency converter, a phase-locked loop generates a local-oscillation signal having a low frequency, of a plurality of local-oscillation signals having different frequencies, based on an intermediate frequency beacon signal that results from mixing a predetermined beacon signal with the local-oscillation frequency signal. Even if the phase-locked loop is used to generate the low frequency local-oscillation signal only, a frequency offset and a phase noise taking place in remaining high frequency local-oscillation signals are compensated for or canceled out. The frequency converter thus results in a high frequency accuracy. This arrangement reduces the number of bulky, costly and power-consuming phase-locked oscillators, typically used in the quasi millimeter band or the millimeter band. A simplified, compact frequency converter is thus provided, reducing both installation and operating costs.
