FAQ
Q1: Tsela ya go Netefatša Tiragatšo ya RF SAW Bandpass Filter?
A: 1) Lekanya Tahlegelo ya go Tsenya (mohlala, -1.5dB go ya go -3dB typ. ka maqhubu a setsi) o diriša 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 ka ± 100MHz offset).
3) Check Return Loss (S11/S22) to ensure impedance matching (e.g., >15dB) ka gare ga passband bakeng sa go naganišiša mo gonyenyane.
Q2: Ditaba tše di Tlwaelegilego & Ditharollo tša Kopanyo ya Filtara ya RF SAW?
A: Taba 1: Tahlegelo ya go Tsenya ya Godimo ye e sa Letelwago goba Ripple ya Passband
Sebaki: Go se swane ga impedance magareng ga filtara le impedance ya go latela/karolo ya PCB ye e dikologilego (ka tlwaelo 50Ω).
Lokiša: Netefatša le go beakanya netweke ya go nyalelanya tsenyo / ditšweletšwa (mohlala, letoto goba di-inductors/capacitors tša shunt) bjalo ka ge go kgothaletšwa ka go datasheet.
Taba ya 2: Go Fokola ga Out-of-Go Gana ga Sehlopha goba go Dutla ga Letshwao
Sebaki: Kopanyo ya EMI go tšwa methopong ya kgauswi yeo e šitišago goba go fa fase mo go sa lekanego godimo ga kotse ya sefa.
Lokiša: Netefatša gore di- paddle tša fase tša filtara di soldered gabotse go sefofane sa fase sa RF se se tiilego. Diriša makotikoti a go šireletša gomme o arole filtara go tšwa go dipotologo tša lešata (mohlala, di-amplifier tša maatla, dišupanako).
