Hello everyone had an email from the admin quoting that I had not posted on hear for 3 months now so i had a slight problem and thought id better post

I need an an amplifier for round about 1800 MHz (3 mobile broadband)
Cant find any for sale so I may have to build one
I was wondering if anyone could be so kind as to point me in the right direction to a web site that has a wiring schematic for my requirements or dose anyone have a schematic tucked away on there PC that they would kindly upload

Thanks

Thanks for that link

I will study it soon and after I probaly will need to ask some questions as to some of the components as Im new to all this

OK
Hear the capacitors required to build the circuit
and hear are some capacitors I found from Maplins
the 1 uf 3 kinds not sure which one to chose though
the 10 pf dose that look OK
And dose anyone know wear I can source the other capacitors
Thanks

For that frequency, I'd suggest surface mount devices. The wavelength is shorter than the leads on some of those caps, which will end up giving you headaches in operation.
