Temperature Behavior of Thin Film Varactor

Abstract

The low loss varactor (voltage tunable capacitor) would revolutionize the wireless communication, sensing, and detecting industries. Temperature behavior plays a critical role in barium strontium titanate (BST) thin-film varactors. In this report, the behaviors of resonant frequency as a function of test time were investigated and discussed. The temperature behaviors of both metal organic deposition (MOD) and pulsed laser deposition (PLD) thin-film varactors were studied from -30 to 80 deg C. The temperature coefficients of thin-film varactors were modeled and calculated
