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.

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.
