amplifier for output of THDB_ADA

I have an OFDM transceiver with SMA output from the THDB_ADA (Terasic) board. I need to amplify this output to drive a line. I am asking for about 1 AMP into a variable load (between 10 ohms to 600 o...

1A into 600 ohms is 600 V. Do you mean it? Not impossible, but it restricts the amplifier offer to a small choice of special high voltage amplifiers, e.g. from APEX/Cirrus. For clarity, you should specify the intended output voltage range and impedance of the amplifier.

THDB_ADA has AD and DA channels have a high pass characteristic by their input and output transformers. For 300 kHz transmission, you possibly should bypass it.
