Raws li tus neeg xa khoom hauv zos tau tsom mus rau siab -SAW lim dej,Suzhou Hangjing Elec & Tech Co., Ltdqhia SF11S5-1575.420-F2.4IL0.9A GPS L1 Surface Acoustic Wave (SAW) lim, tsom rau 1575.42MHz tus qauv GNSS band. Nws qhov kev ua tau zoo yog piv rau cov khoom lag luam thoob ntiaj teb los ntawm Murata, TDK, thiab Qorvo, muab cov khoom siv ruaj khov thiab kev tswj xyuas hauv tsev rau kev tso chaw terminals.
1. Basic Parameters & Core nta
Tsawg Insertion Poob
Center zaus: 1575.42MHz
Kev xa tawm bandwidth: 2.4MHz
Insertion poob: 0.9dB raug, 1.3dB max
Amplitude ripple: Tsawg dua lossis sib npaug rau 0.5dB
→ Ua kom lub siab rhiab heev rau qhov chaw txais lub teeb liab.
Nruab Nrab Tawm- ntawm -Band Rejection
Ze ntawm - kawg tawm - ntawm -band tsis lees paub: 42–47dB
→ Zoo cais tawm sab nraud RF cuam tshuam los ntawm LTE, 5G, thiab lwm yam, txo txoj haujlwm drift thiab satellite tau ncua qeeb.
Me me Standardized Pob
Pob loj: 1.4 × 1.1 × 0.6mm - zoo tib yam rau Murata tib yam - cov khoom tshwj xeeb, ncaj qha sib xws thiab hloov tau. Piv nrog rau cov qauv TDK loj dua, nws zoo dua haum cov qauv PCB hauv cov khoom siv coj los hnav thiab nqa tau.
Standard Wide -Tsuas Ua Haujlwm
Kev khiav hauj lwm kub: -30℃rau +85℃- npog feem ntau ntawm pej xeem ib puag ncig rau hauv-tsheb, drone, thiab IoT davhlau ya nyob twg daim ntawv thov.
Cia qhov kub thiab txias: -40℃txog +85℃- ua tau raws li qhov yuav tsum tau muaj kev cia thiab kub sab nraum zoov.
RoHS Raws Cai & Ntsuab Tsim
RoHS coj-dawb raws, nrog cov txheej txheem tsim khoom thiab xa khoom.
2. Lub Hom Phiaj Sib piv nrog Cov Hom Tshuaj Thoob Ntiaj Teb
Kev sib piv ncaj qha nrog cov ntxaij lim dej tseem ceeb GPS los ntawm Murata, TDK, thiab Qorvo:

Insertion poob (0.9dB hom) yog nyob rau hauv lub mainstream ntau thiab zoo dua li ib co TDK series.
VSWR (1.2 hom) sib tw Murata thiab TDK.
Tawm - ntawm -band rejection (42-47dB) ua tau raws li qhov xav tau los tiv thaiv kev cuam tshuam rau cov cuab yeej siv rau pej xeem pom zoo.
Kev khiav hauj lwm kub suits feem ntau hauv tsev davhlau ya nyob twg scenarios; zuag qhia tag nrho kev ua tau zoo mus txog ib theem siv tau.
3. Lub Hom Phiaj Daim Ntawv Thov
Haum rau ntau yam GPS / GNSS qhov chaw terminals, suav nrog:
Automotive navigation & T-BOX
Drone avionics

4. Kev Tshawb Fawb Kev Ntseeg
Cov khoom lag luam tau ua tiav tag nrho cov kev ntsuam xyuas kev ntseeg siab thiab ua tau raws li kev lag luam -qib tus qauv yuav tsum muaj:
Ntev - lub sij hawm cia ntawm qhov kub thiab txias
Siab - kub, siab - av noo endurance
Pua pua ntawm qhov kub thiab txias mus
Reflow soldering tsis kam
Kev xeem Solderability
Kev ua tau zoo sib xws hauv kev tsim khoom loj
5. Kev them nyiaj yug los ntawm HCI
Suzhou Hangjing Elec & Tech Co., Ltdtsim thiab tsim SAW cov ntxaij lim dej hauv -lub tsev, ua kom muaj kev tswj hwm hauv tsev thiab ruaj khov ntim khoom. Peb muab cov ntaub ntawv pov thawj, cov qauv kuaj, thiab kev txhawb nqa dav dav.
