FAQ
Q1: Pehea e hōʻoia ai i ka hana o kahi kānana Bandpass RF SAW?
A: 1) E ana i ka poho hoʻokomo (e laʻa, -1.5dB a -3dB typ. ma ke alapine waena) me ka 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 ma ± 100MHz offset).
3) Check Return Loss (S11/S22) to ensure impedance matching (e.g., >15dB) i loko o ka passband no ka noʻonoʻo liʻiliʻi.
Q2: Nā pilikia maʻamau a me nā hoʻonā no RF SAW Filter Integration?
A: Puka 1: Nalo hoʻokomo kiʻekiʻe i manaʻo ʻole ʻia a i ʻole Passband Ripple
Ke kumu: Impedance mismatch ma waena o ka kānana a me ka PCB trace/component impedance (maʻamau 50Ω).
Hoʻopaʻa: E hōʻoia a hoʻoponopono i ka ʻupena hoʻokomo a i waho (e laʻa, series a shunt inductors/capacitors) e like me ka mea i ʻōlelo ʻia ma ka ʻikepili.
Puka 2: Loaʻa ʻole i ka --hōʻole ʻana i ka pūʻali
Ke kumu: Hoʻopili ʻia ʻo EMI mai nā kumu hoʻopilikia kokoke a i ʻole ka lawa ʻole o ke kahua ma ka pale kānana.
Hoʻoponopono: E hōʻoia i ke kūʻai pono ʻia ʻana o nā hoe lepo o ka kānana i kahi mokulele honua paʻa RF. E hoʻohana i nā kini pale a hoʻokaʻawale i ke kānana mai nā kaapuni walaʻau (e laʻa, nā mea hoʻonui mana, nā uaki).
Nā huahana pale: Ua ʻike ʻo rf i ka kānana bandpass 3 x 3 x 1.25, Kina rf i ʻike i ka kānana bandpass 3 x 3 x 1.25 nā mea hana, nā mea hoʻolako.
