Hello
i want to design an amplifier to radiate a 950-1800 mhz signal from my source in 150 meter radius or more than that
i don`t know where to start
if any one help me with this i`ll be very grateful
Thank you

well it`s for jamming circuit that radiate 30 meter maximum
i want a separate circuit that feed from the rf section and amplify the signal so that it cover larger area
Thanks

it`s for studying purpose
what i`m missing is the gain
it`s not designed for jamming as it`s designed for securing specific radius
so 30 meter will be not enough
the BW 925-970 && 1785-1900 MHZ
Those are the frequicy range

ok
the if section is finished which i used 555 timer+ lm386 to lm 741 which is the o/p to the rf section
signal from if go to rf will pass through 2 vco (925-970 vco) & (1785-1900 vco)
the o/p of each vco goes to mosfet then the o/p of each mosfet goes to antenna
or to a separate unit to amplify the signal with it`s own power supply if it`s possible
