In Progress

Design a simple (pre)amplifier circuit - push pull class AB

We need someone to design a pre-amplifier (not a LNA, we need a current amplifier) circuit, ONLY the circuit (not the PCB) for those characteristics :

Input Signal:

Sinusoidal AM

Frequency between 12 and 14 MHz

Power : [url removed, login to view] (11dbm)

Vpp : arround [url removed, login to view] ([url removed, login to view])

Impedance : 50 ohm

Output Signal :

Same signal with as little distortion as possible, no frequency shift

Vpp : same as the entry as possible

Power output : 16dbm - 40mW

Impedance : 50 ohm

Ideally if you could use 2N3904/2N3906 or 2N2222A/2N2907 as for the transistor (We already have those in stock) it would be great but you can use whatever you need.

This is an URGENT project.
