FAQ

Q1: Bii o ṣe le rii daju Iṣe ti Ajọ Bandpass RF SAW kan?

A: 1) Wiwọn Pipadanu Ifibọ sii (fun apẹẹrẹ, -1.5dB si -3dB tẹ. ni igbohunsafẹfẹ aarin) nipa lilo Oluyanju Nẹtiwọọki Vector (VNA).
2) Characterize Bandwidth & Selectivity by plotting S21 to determine -1dB and -3dB bandwidths and out-of-band rejection (e.g., >25dB ni ± 100MHz aiṣedeede).
3) Check Return Loss (S11/S22) to ensure impedance matching (e.g., >15dB) laarin iwe iwọle fun iṣaro diẹ.
