Claims

[Scope of utility model registration request]

An oscillator unit with a local inductor provided near one side of the case is arranged so that the output inductor on the board on the bottom of the case body is located between the local inductor and the side of the case. A component arrangement structure of a modulator, which is arranged so as to face an output terminal provided on one side of a case body, and predetermined electronic components are assembled in a substantially straight line between the output take-out inductor and the output terminal. .
