Cov FAQ

Q1: Yuav ua li cas txheeb xyuas qhov kev ua tau zoo ntawm RF pom lub lim bandpass lim?

A: 1) Ntsuas cov ntxig nyiaj poob (piv txwv li, -1.5db rau -3db txuas. Ntawm qhov chaw nruab nrab) Siv Vector Network Analyer (VNA).
2) Characterize Bandwidth & Selectivity by plotting S21 to determine -1dB and -3dB bandwidths and out-of-band rejection (e.g., >25DB ntawm ± 100MHz offset).
3) Check Return Loss (S11/S22) to ensure impedance matching (e.g., >15db) nyob rau hauv passband rau tsawg kawg kev xav.

Q2: Cov teeb meem ntau yam & Cov kev daws teeb meem rau RF pom kev lim kev koom ua ke?

A: Qhov teeb meem 1: Npaj txhij txog qhov siab dua siab poob lossis passband ripple
Cause: impedance mismatch ntawm lub lim thiab ib puag ncig PCB trac / meteent impedance (feem ntau).
Txhim kho: Tshawb nrhiav thiab kho cov tswv yim / tso zis sib txuam Network (piv txwv li, series lossis shuntorors / capacitors) raws li pom zoo hauv Datasheet.
Qhov Teeb Meem 2: Tsis Zoo {{1} {- kev tsis lees txais los yog teeb liab queakage
Cause: EMI sib txuas los ntawm kev cuam tshuam ze rau cov peev txheej lossis tsis txaus ntawm lub lim ntaub thaiv.
Txhim kho: kom lub lim lub lim hauv av paddles yog solded kom zoo rau cov khoom siv RF av dav hlau. Kev siv cov kaus poom thiab cais cov lim thiab cais cov lim los ntawm nrov nrov hluav taws xob (piv txwv li lub zog hluav taws xob, cov moos).
