FPV Analog Video Transmitter CVBS audio video module sender 400-900MHz UHF vcan1904

Tirohanga

No UHF tenei kōwae Ko nga taputapu whakawhitiwhiti reo irirangi i roto i te roopu auau, ka taea te tuku ororongo me te ataata i roto i te awhe iti. I hangaia mo te iti o te kohi hiko, VCO whakauru, PLL, me AM aunui whakahekenga ataata, Ko te auau kawe oro ka iti ake te kōwae; ka tangohia e ia he kete iti-poari iti, he watea mo nga kaiwhakamahi ki te whakaiti i nga tono.

Ko te tono o tenei kōwae me hono noa te tuku hiko, taura ororongo, me te taura ataata, me te hono i te antenna ki te whakamahi i nga momo momo taputapu hiko e tautoko ana i te powhiri pouaka whakaata tairitenga, tae atu ki nga waea pūkoro, TV, rorohiko pona, MP4, me nga whakaahua matihiko.

Āhuahira

1. UHF AM aunui tukunga
2. rahi iti: 17*16.5*4.5mm
3. Wmahi ngaohiko ide: 3.3-4.2V
4. kohi mana iti:3.3V 180mA
5. Te mana whakaputa teitei:17dBm
6. Hanga-i roto i te auau wāhanga-rakaa koropiko tiketike pūmautanga
7. Te whakarerekētanga tika o nga tohu ororongo me te ataata
8. E waru nga hongere ka kiia he ngawari
9. Chipset ASE373C

Taupānga

1. Hewaea nalog tv
2. VCD/DVD/DVB ororongo/Whakawhiti ahokore ataata;
3. Te aroturuki pepi;
4. Aroturuki whakaahua i runga i te waahi tuuturu;
5. Pūnaha tuku haumaru;
6. PSP ka huri keemu te TV
