    摘要： The invention seeks to provide a high-frequency composite component capable of: simplifying the circuits from the antenna to the input side of the high-frequency amplifier circuit; suppressing a loss in the signal; and reducing the cost and the size, when a wireless system using plural frequency bands, such as a wireless LAN system using plural frequencies, is constructed. The high-frequency composite component is fabricated by placing an antenna 1 on a multi-layer wiring board 41, placing a multiplexer/demultiplexer circuit 2, matching circuits 3 and 4, and balanced-to-unbalanced transformer circuits 5 and 6 inside the board 41 respectively, and providing input and output terminals 7 through 10 on the side surface of the board 41. The antenna 1 is connected to the multiplexer/demultiplexer circuit 2 via an unbalanced line path 11, and the multiplexer/demultiplexer 2 is connected to the matching circuits 3 and 4 via unbalanced line paths 12 and 13, respectively. The matching circuits 3 and 4 are connected to the balanced-to-unbalanced transformer circuits 5 and 6, respectively, via unbalanced line paths 14 and 15, respectively. The respective balanced terminals of the balanced-to-unbalanced transformer circuits 5 and 6 are connected to the input and output terminals 7 and 8, and 9 and 10, respectively, via balanced line paths 16 and 17, respectively.

    摘要： Disclosed is an oscillator that can be flexibly retrofitted to become usable for a wide range of applications and to become compatible with different users' requests, and that enables a user to design a high-frequency unit using the oscillator without concerns. The oscillator includes a SAW resonator (1) and an oscillation unit (2) provided in the form of an integrated circuit. The SAW resonator and oscillation unit are encapsulated in the same package and then sealed. The whole oscillator is thus provided in the form of a module. The oscillation circuit (4) includes an adjustment terminal (9) with which a current flowing through a current source (8) is adjusted externally. A resistor (R3) offering a desired resistance is connected between the adjustment terminal (9) and a ground terminal (7), whereby a negative resistance can be adjusted. Moreover, an adjustment terminal (10) with which a current flowing through a current source in an amplification circuit (5) is included. A resistor (R4) whose resistance permits an output of a desired intensity is connected between the adjustment terminal (10) and the ground terminal (7). Thus, the intensity of the output can be adjusted.
