摘要： An antenna switch module includes a filter which reduces transmission loss so as to achieve high attenuation in a wide band at harmonic frequencies. This antenna switch module includes the filter, an antenna switch circuit and an adjustment line. The filter passes fundamental frequencies and has an attenuation pole. The antenna switch circuit switches antennas. The adjustment line is connected between the filter and the antenna switch circuit. The adjustment line adjusts its length, and when the filter and the antenna switch circuit are directly connected with each other at a connection point, prevents the impedance when the filter is seen from the connection point and the impedance when the antenna switch circuit is seen from the connection point from becoming complex conjugates of each other at the harmonic frequencies.

摘要： A buckling actuator has a connecting section of a supporting beam that is provided with a rotatable supporter for allowing a movable member to be stably maintained at one of two switch positions. A substrate, stationary members, rotatable supporters, and supporting beams support a movable member in a shiftable manner in a y-axis direction, such that the movable member can be shifted between first and second switch positions. Moreover, the rotatable supporters are each provided with arm portions which extend in a radial fashion and support the corresponding supporting beam in a rotatable manner. When the movable member is being shifted, each supporting beam scan be rotated without having to bend a corresponding end by a significant amount. Thus, a large barrier ΔE of potential energy of the movable member is set between the first and second switch positions. The movable member can therefore be stably maintained at each of the switch positions even when electric power is not supplied to electrodes. Furthermore, each arm portion prevents the movable member from being displaced in an x-axis direction.

摘要： A composite filter downsized without degrading its characteristics is disclosed. The filter includes a surface acoustic wave filter and an LC filter coupled to the surface acoustic wave filter. The LC filter is formed by combining a π-shaped LC filter formed of two capacitors and an inductor coupled together in a π-shape with a capacitor coupled in parallel to the inductor. The two capacitors of the π-shaped LC filter are placed on a piezoelectric substrate with their comb-shaped electrodes opposed to each other. This opposing direction differs from an opposing direction of comb-shaped electrodes of a surface acoustic wave resonator.
