摘要: In this paper, a quantitative analysis to obtain the equivalent circuit parameters of helix-on-pads (HoPs) is presented. To simplify analysis, HoP, which kind helical wires vertically mounted on dielectric substrate, subdivided into two parts using split-up method based field distribution. The derives RLGC formulas HoPs for various dimensions and number loops. verify accuracy derived model, electromagnetic (EM) simulations cases are also performed. EM-simulated results show good agreement with calculated results. experimentally demonstrate usefulness designed fabricated W-CDMA dual-band (Band-2 Band-5) handset power amplifier (PA) applications. Measured RF performances standalone composite PA agreements results, thus validating design.
