<P>PROBLEM TO BE SOLVED: To provide a high frequency circuit apparatus, a high frequency module, and a wireless communication apparatus for reducing the power loss, improving a circuit operation characteristic, and preventing abnormity oscillation by attenuating a PPM leaky wave propagated in a board. <P>SOLUTION: The high frequency circuit apparatus includes slot lines 1, 2 and a FET 200 which are located on a front side of a dielectric board 100, and slot lines 3, 4 configuring a PDTL asymmetric to the slot lines 1, 2 and which are located on a rear side of the dielectric board 100. Grounded conductor plates 5-1, 5-2 are fitted to both sides of the dielectric board 100, an upper side 52 of the conductor plate 5-1(5-2) is in contact with a front side conductor 101 and a lower side 53 is in contact with a rear side conductor 102 respectively, so as to short-circuit the front side conductor 101 and the rear side conductor 102 by the conductor plate 5-1(5-2). Further, an air gap 55 is demarcated between a board end 100a (100b) of the dielectric board 100 and an upright part 51 of the conductor plate 5-1(5-2) to open the board end 100a (100b). <P>COPYRIGHT: (C)2008,JPO&INPIT |
