    摘要： A small and thin plane type narrow-band dielectric filter to be used for a portable telephone and the like, includes a plurality of end short-circuited strip line resonators having a length of about quarter-wavelength formed parallel and closely to each other on a first dielectric substrate and directly magnetically coupled to each other. The thus formed strip line resonators are partially bonded to parallel plane capacitor electrodes formed on a second dielectric substrate in respective overlapping areas thereby electrically coupling the strip line resonators through the parallel plane capacitors, so that the inter-resonator coupling can be reduced due to the fact that it is achieved in combination with the magnetic coupling and the electrical coupling.

    摘要： A linear amplifier has an input signal controller for controlling the level of an input signal to a field-effect transistor (FET) using a DC gate current measured by a gate current detector arranged between a gate bias terminal and a drain bias terminal of the FET and a nonlinear resistor whose resistance can be varied corresponding to an inter-terminal voltage between the gate and the drain of the FET, in which the voltage at the gate of the FET is adjusted to a rate such that a particular drain current which has been determined just before the starting of burst signal transmission corresponding to the level of a power output of the linear amplifier is obtained, and is maintained for a given period of time.

    摘要： This invention offers a compact and high performance dielectric filter consisting of a quarter wavelength dielectric body provided with a through-hole between the upper and lower surfaces of the dielectric body, electrodes deposited on external and lower surfaces of the dielectric body, and at least two independent electrodes provided on an internal surface of the through-hole, extending to the upper and lower surfaces of the dielectric body. With this dielectric filter construction, the through-hole performs the role of constructing plural quarter wavelength resonators and performs, at the same time, the role of adjusting the coupling between the plural resonators, thus yielding a compact dielectric filter of simple construction.
