Whakaahuatanga Hua
Kupu Whakataki
Ko te kaiwhiwhi whatu raupapa SRB he momo kaiwhiwhi whatu ā-roto whai hua i hangaia hei whakatutuki i te kaupapa whakahoutanga muka whatunga. E 1 ki te 2 ngā putanga putanga RF o tēnei hua. Ā, ka taea te pupuri i te mahi AGC whatu ina +2dBm ~ -6dBm i te wā e whiwhi ana i te putanga ki te 106dBµV i runga ake nei (takirua); mā te anga e whakamahi ana i te anga konumohe whakarewa.
Ngā Āhuatanga Mahi
- Pūhara whānui 45MHz ki te 1000MHz me te pūhara hoahoa matapihi takirua 1310, 1550;
- He ara iahiko tino pai mō te pehi ngaru me te tātari whakawhiti-teitei, me te ātete kaha ki ngā whiunga uira me te ārai i te pānga o te ngaru;
- He hoahoa iti te whakamahinga hiko, he iti iho i te 15W te whakamahinga hiko katoa; ā, he whakaaturanga mamati me te mahi whakahaere ipurangi.
- Ka taea te whakamahi i ngā transponder Momo II;

| Kia mōhio: I raro i ngā tikanga ngaronga hononga kua tohua, whirihorahia ngā tohu hongere pouaka whakaata PAL-D anarau 59 i roto i te awhe auau 550MHz, ka tuku tohu whakarerekētanga mamati i roto i te awhe auau 550 MHz ki te 862MHz. Ko te taumata o te tohu whakarerekētanga mamati (i roto i te whānui o te 8 MHz) he 10dB iti iho i te taumata kawe o te tohu anarau. Ina he 6 dBm te mana whatu whakauru o te kaiwhiwhi whatu, inehia a C/CTB, C/CSO, me C/N. Ko te taumata putanga RF ingoa kei te pūwāhi auau 862 MHz, ko te putanga tuturu he 10dB iti iho. | |||
