I need to select a power amp to match as the last stage to a previous preamp circuit.
Let's leave out for a moment the laws, regulations, usable frequencies and powers, as currently it is a simulation, this pre-amplification circuit in simulation allows to supply in sinusoidal it will be able to supply from 20mV (+/- 10mVolt) to 2Volt (+/- 1Volt) up to 100MHz then the power amp can be driven with this voltage depending on the stages used. The most important factor is the phase linearity up to 100Mhz and I thought it could be done as there are devices on the market with a bandwidth of several GHz. Without this factor I don't need it. I would prefer to use FETs but all the amps I've tested from J-FETs (very sensitive and ideal) and Mosfets don't have phase linearity. The use of Mosfets is not excluded because even if they use higher input voltages and for this reason I have put as a limit of voltage supplied by the preamplifier up to 1Volt. Furthermore, it could drive low ohmmic loads without any particular problems. Advice on which component to use?
