PROBLEM TO BE SOLVED: To provide a high frequency device with ease of adjustment. SOLUTION: The high frequency device includes an input terminal 21 which receives a high frequency signal, an adjustable dual tuning circuit 24 that receives the signal received by the input terminal 21, an intermediate frequency amplifier circuit 27 that receives an output of the dual tuning circuit 24 and provides balanced outputs, a balanced SAW filter 29 that receives an output of the intermediate frequency amplifier circuit 27, and an output terminal 31 that receives balanced outputs from the SAW filter 29. The balanced outputs of the intermediate frequency amplifier circuit 27 are led out to inspection terminals through two conductors while keeping the balancing state. Thus, the adjustment of the high frequency device can be facilitated.
