€30-250 EUR

Paid on delivery
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 : 12.5mW (11dbm) Vpp : arround 3.3Vpp (3Vpp-3.5Vpp) 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.
