FAQ
I-Q1: Indlela yokuqinisekisa ukuSebenza kwe-RF SAW Bandpass Filter?
A: 1) Ukulinganisa ilahleko yokuFaka (umzekelo, -1.5dB ukuya kwi-3dB isimbo. Kwiziko elijikelezayo) usebenzisa iVector Network Analyzer (VNA).
2) Characterize Bandwidth & Selectivity by plotting S21 to determine -1dB and -3dB bandwidths and out-of-band rejection (e.g., >I-25dB kwi-± 100MHz offset).
3) Check Return Loss (S11/S22) to ensure impedance matching (e.g., >15dB) ngaphakathi kwebhendi yokupasa ukuze ubonise kancinci.
I-Q2: Imiba eqhelekileyo kunye nezisombululo zeRF SAW Filter Integration?
A: Umba 1: Ilahleko yokuFaka okuphezulu okungalindelekanga okanye i-Passband Ripple
Unobangela: Ukuphazamiseka kokungahambelani phakathi kwesihluzi kunye nePCB ejikelezileyo umkhondo/ukuphazamiseka kwelungu (ngokwesiqhelo yi-50Ω).
Lungisa: Qinisekisa kwaye ulungelelanise igalelo / imveliso ehambelana nenethiwekhi (umzekelo, uchungechunge okanye i-shunt inductors / capacitors) njengoko kucetyiswa kwidatha yedatha.
Umba wesi-2: Ayilunganga{1}ku{2}}kuKwaliwa kweBand okanye ukuvuza koMqondiso
Unobangela: Ukudibanisa kwe-EMI ukusuka kwimithombo ephazamisayo ekufutshane okanye ukungonelanga komhlaba kwikhuselo lokucoca.
Lungisa: Qinisekisa ukuba amaphini okucoca aphantsi athengiswa ngokufanelekileyo kwinqwelomoya eqinileyo yeRF. Sebenzisa iinkonkxa ezikhuselayo kwaye wahlule isihluzo kwiisekethe ezinengxolo (umzekelo, izikhulisa-mandla, iiwotshi).
