Fa'amama fa'alogo mo VHF 152-174MHz
Fa'amama fa'alogo mo VHF 152-174MHz,
Tufuga o RF faamama,
Fa'amatalaga
VHF Tunable Filter o lo'o fa'agaoioia mai le 152-174MHz ma N Feso'ota'i
VHF faamama JX-SF1-152174-215N o se tasi ituaiga o faamama tunable mo VHF faagaoioia mai le 152-174MHz ma le bandwidth o le 5-15MHz. E mafai ona tunable e tusa ai ma le manaoga tonu pe a faʻaaogaina, faʻatasi ai ma le vaega o le faʻaofiina. leiloa i lalo ole 0.5-2.2dB i bandwidths eseese, toe faafoi leiloa o le sili atu i le 20dB, ma maualuga teena foi.
O lea ituaiga o faamama o lo'o fuafuaina mo le fa'alogoina o lona taimi e tusa ai ma le taimi fa'alogo, ina ia mafai ona fa'aaoga lautele mo fofo VHF. I le avea ai ma RF filter designer, o le tele o filiga faʻalogo e mafai foi ona faʻapitoa. E pei ona folafola mai, o vaega uma RF passive mai Jingxin e 3 tausaga faʻamaonia.

Fa'asinomaga RF Passive Vaega
I le avea ai ma se gaosiga o vaega passive RF, e mafai e Jingxin ona mamanuina mea eseese e tusa ai ma talosaga a le au faipisinisi.
Na'o le 3 Laasaga e foia ai lou fa'afitauli o le RF Passive Component
1. Fa'amatalaina le parakalafa e oe.
2. Tuuina atu le talosaga mo le faʻamaoniga e Jingxin.
3. Fausiaina o le faʻataʻitaʻiga mo le faʻataʻitaʻiga e Jingxin.
