FAQ
Q1: Kumaha Mariksa Kinerja Saringan Bandpass RF SAW?
A: 1) Ukur Insertion Loss (misalna -1.5dB mun -3dB typ. dina frékuénsi puseur) ngagunakeun 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 dina ± 100MHz offset).
3) Check Return Loss (S11/S22) to ensure impedance matching (e.g., >15dB) dina passband pikeun réfléksi minimal.
Q2: Masalah Umum & Solusi pikeun Integrasi Filter RF SAW?
A: Masalah 1: Kaleungitan Insertion Tinggi anu teu kaduga atanapi Ripple Passband
Cukang lantaranana: Impedansi mismatch antara saringan jeung PCB sabudeureun renik / impedansi komponén (ilaharna 50Ω).
Ngalereskeun: Verifikasi tur saluyukeun input/output jaringan cocog (misalna runtuyan atawa shunt induktor/kapasitor) sakumaha dianjurkeun dina lembar data.
Masalah 2: Kurangna -tina -Tanggapan Pita atanapi Bocoran Sinyal
Cukang lantaranana: EMI gandeng ti sumber interfering caket dieu atawa grounding cukup dina tameng filter.
Fix: Pastikeun paddles taneuh filter urang soldered leres ka pesawat taneuh RF padet. Anggo kaléng pelindung sareng ngasingkeun saringan tina sirkuit anu ribut (contona, amplifier listrik, jam).
