FAQ
Q1: Yadda Ake Tabbatar da Ayyukan Tacewar Fassara na RF SAW?
A: 1) Auna Asarar Sakawa (misali, -1.5dB zuwa -3dB nau'in. a tsakiyar mita) ta amfani da Vector Network Analyzer (VNA).
2) Characterize Bandwidth & Selectivity by plotting S21 to determine -1dB and -3dB bandwidths and out-of-band rejection (e.g., >25dB a ± 100MHz biya diyya).
3) Check Return Loss (S11/S22) to ensure impedance matching (e.g., >15dB) a cikin lambar wucewa don ƙaramin tunani.
