Faa'iidooyinka iyo Codsiyada filtarrada Tunable-ku-salaysan ee Chip-ku-salaysan
Faa'iidooyinka Farsamada: Waxaan nahay kuwa ugu horreeya warshadaha adduunka oo dhan si aan u gaarno horumar tignoolajiyadeed ee 1.5-700 MHz tignoolajiyada shaandhada chip-tunable, oo muujinaya faa'iidooyinka hormuudka ah ee aan loo baahnayn sahayda korantada sare, isticmaalka korantada aadka u hooseeya, cabbirka aadka u kooban, iyo culeyska khafiifka ah.
■ Faa'iidooyinka Halbeegga: Kala duwanaanshaha korantada shaqeynaya: +3.3V ilaa +12V, oo leh nidaam caadi ah isticmaalka hadda ee 6-8 mA. Faa'iidooyinka waxaa ka mid ah cabbirka is haysta, naqshadaynta miisaanka fudud, iyo isticmaalka tamarta yar.
■ Codsiyada: Isgaarsiinta moobilka, isgaarsiinta soo noqnoqda, SDR (raadiyaha ku qeexan software), qalabka tijaabada iyo cabbiraadda, qalabka caafimaadka, iyo goobaha kale ee codsiga.

Waa maxay sababta aan u dooranay filtarradayada SDR Wideband?

Deegaannada casriga ah ee RF waa kuwo aan la saadaalin karin. Shaandhooyinka bandpass ee go'an ayaa inta badan gaabsada marka aad u baahan tahay karti. Xalalka shaandhayntayadu waxay isku daraan qalabka qallafsan iyo dabacsanaanta gees-goynta, hubinta in goobtaada SDR ay ku shaqeyso waxtarka ugu sarreeya iyada oo aan waxyeello loo geysan baaxadda firfircoon.

Daboolista Soo noqnoqoshada aadka u Balaadhan: Waxaa loo naqshadeeyay si aan kala go 'lahayn si loo taageero codsiyada bandwidth-sare ee HF, VHF, UHF, iyo mikrowayt.

Luminta Gelida Hoose & Diidmada Sare: Soo saarista signalka ugu badan ee meesha aad uga baahan tahay, iyo dhumuc qoto dheer halka aanad u baahnayn.

Is-dhexgalka Is haysta & Rugged: Ku Fiican SWAP (Xajmiga, Miisaanka, iyo Awoodda) deegaan xaddidan, laga bilaabo meelaynta goobta ilaa baaritaanka shaybaadhka.

Descriptions	Address Code Definition: 10-bit parallel binary code A0–A9, compatible with CMOS and TTL logic levels. · A0–A7 control voltage levels: Logic Low: 0 ~ 0.7 V; Logic High: 2.4 ~ 3.3 V . · A0–A7 are used as the in-band address code. · A8 and A9 are used as band selection codes. Address Calculation (rounded to integer) Address Code={(fx-flow）/(fhigh-flow)}*250 Where: · fx: desired intrasegment center frequency · flow: lowest frequency in the segment · fhigh: highest frequency in the segment · 250: intrasegment steps If the calculated result contains a decimal fraction, it shall be rounded to the nearest integer.
