150 Watts BLF177 FM broadcast (87,5-108MHz) RF-broadband amplifier
==================================================================

The amplifier requires max. 8 Watts rf-drive to deliver 150 Watts output power.
Supply voltage : 50 Volts, adjust bias to approx. 1,8 Volts.


CuAg = silver plated copper wire
CuL = magnetwire, enameled copper wire
(Note: 1 mm CuL equals approx. to AWG18
0,3 mm equals approx. to AWG28)

(I) all diameters are measured from the inside of the coils
(II) make sure to mount the rf-transistor on a appropriate heatsink and use some thermal
heatsink compound between the stud of the rf-transistor and the heatsink!
(Thermal resistance heatsink at least 6°C/W.)
(III) all parts are soldered directly on the toplayer of the pcb
(IV) connect the bottomlayer to the groundplane on the toplayer!

penguat ini memerlukan max. 8 Watts rf-drive untuk memberikan daya output 150 Watts.
tegangan Supply: 50 Volt, menyesuaikan bias ke approx. 1,8 Volts.


CuAg = perak berlapis kawat tembaga
CUL = magnetwire, kawat tembaga berenamel
(Catatan: 1 mm CUL sama dengan kira-kira. Untuk AWG18
Kira-kira sama dengan 0,3 mm. untuk AWG28)

(I) semua diameter diukur dari bagian dalam kumparan
(II) pastikan untuk me-mount rf-transistor pada heatsink yang sesuai dan menggunakan beberapa termal
heatsink senyawa antara stud-rf transistor dan heatsink!
(Heatsink Termal resistensi setidaknya 6 ° C / W)
(III) semua bagian sudah disolder langsung pada toplayer dari PCB yang
(IV) bottomlayer menghubungkan ke groundplane pada toplayer ini!​
