ya sudah.kalau ini sih memang produk warehouse.dan memang bang Ahim memang salah satu referensinya dari warehouse.lihat pada pemasangan trimer condensator dekat output rakitan bang Ahim.kan tidak orisinil sesuai desain asli pcbnya.but,by the way.no problema..........!
-
Kalo ini gimana?? gak pake trimer.. mantap... awet... adem.. inputnya macth

2SC2782 di datasheet buat 80 Watt, kalau hasil test sheet memang bisa lebih dari 100 Watt. tapi biasanya kalau buat dipakai pemancar yang kontinue on air lebih baik jangan lebih dari 80 Watt, biar awet

mau tanya nih saya kan beli rangkaian pemancar FM 10mWatt trus bisa gx untuk nendang rangkaian penguat sinyal RF 100watt ini??kalo bisa dan ada yg mau menjualnya saya ingin beli.maklum nubi..... ^_^ atau jika ada yang tahu solusinya????

Waduh jauh banget yah ? paling tidak butuh Power input 20 watt an buat nge drive 100 watts..
10 mW ? ni ngak salah tulis ....
-
kang jack bagi donk layoutnya...pengen nyoba pake 2630..... drop1

iya bener mas,itu gx salah nulis.emang belinya yg segitu.mas bisa ngadain kit PA 20Watt yg bisa ditendang dgn inputan daya 10mili volt ini.atau ada solusi lain? ^_^
-
upss...maaf maksudnya bukan 10 milli volt tp 10 milli watt.... :-D
-
paling tidak membutuhkan 4 kali penguatan neh baru kuat ndorong 100Watt

yess lutfi thanks for u sorry for posting in english i dont speak indo in fact i made these long time ago 5 years with 2sc2782 and mrf 247 but i lost the pcb layout and want to make another amplifier to my freind if u have the pcb layout share it please thanks
-
hi radium i am sorry....i have not PCB layout like at picture....his jeckoexxel have this PCB layout....but he difficult contact....i wish have layout like at picture because PCB Amplifier is NICE top1 broadband capability....
now i only make RF power amplifier with trial & error with poor yield..
in indonesian metode COBA - COBA..... ^-^ :( :( :( .... build amplifier with broadband for me is difficult & confused...
thanks
Lutfi
