Abstract(in English) | GaAs one Chip Anti-Series Varactor Pair (ASVP) was trial manufactured. Its third-order intermodulation (IM3) distortion generated from nonlinearity of capacitance-voltage characteristics of the ASVP is measured at 2.484GHz. IM3 distortion of the chip is suppressed by approximately 2.8dB from the level of a single varactor (SV). However, the distortion is not satisfied when compared with the result of theory. Consequently, extraction of parasitic impedance is carried out. We find that there are a series-resistance of 500 Ω and a parallel-capacitance of 4 pF exist in the chip. Moreover, impurity distribution coefficient (γ) of the chip is found as 0.827 which is different with the designed value of 0.5. Which is also believed to be the cause of not so good suppression of IM3 distortion. |
