The parallel inductance and capacitance transform the small real-valued conductance of the QPC to a complex admittance with large modulus that is dominated by the coil. The imaginary part of this combined impedance is compensated for by the tunable capacitance in series, and only the small real value close to 50 remains.

Contrary to the predominant matching techniques, the QPC is not directly bonded to the matching circuit but sits in a chip socket, soldered to the high-frequency printed circuit board (pcb) containing the C-LCR matching circuit. This suffers from larger chistray capacitance (∼2.8 pF) but increases the versatility of the setup, as the sample does not have to be designed to fit the pcb. In particular, the setuis compatible with samples fabricated for conventional platforms. See also, 0034-6748,. 10.1063/1.3030860
