    • It is an object of the present invention to provide a high-frequency oscillating circuit that does not have its characteristics such as an S/N ratio degraded by an external electromagnetic interference, wherein the bases of a first and a second oscillating transistors are connected together directly or via a capacitor having a sufficiently low impedance at an oscillating frequency and wherein a differential signal output is obtained from between the emitters of the first and second oscillating transistors as an oscillating output. It is also an object of this invention to provide a resonating circuit for an oscillating circuit which can provide a high Q factor and a high-frequency oscillating circuit using this resonating circuit in order to allow an oscillating circuit IC to have a high C/N ratio. A resonator, varactor diodes, and capacitors and chokes constituting a resonating circuit for an oscillating circuit IC are integrated together as a module separate from a negative-resistance generating circuit including oscillating transistors configured as an IC.
