Transformer Selection for 85-170 MHz AC source

Hello and thanks for your time,

I would like to increase the voltage from an AC source (85 mHz to 170 mHz) from 6.3 V peak-to-peak to 28 V peak-to-peak using a transformer. In my circuit, the AC source has an output impedance of 50 ohms, and the load has an input impedance of 50 ohms.

To achieve the voltage ratio of 4.5 I believe I need an impedance ratio of ~20.

  1. Could anybody recommend a transformer that might work for my application?

  2. Should I be concerned about impedance matching reducing the power on my load due to the high impedance ratio of the transformer?

  3. If so, can you recommend a power amplifier that would maintain the 28 V peak-to-peak voltage, but increase the current across the load.

  4. Is there any other information you need to help me select an appropriate transformer?

Thank you,
