Simple Amplifier 2.5V to 10V with f=13.56MHz

[roobb]

Hi all,

I would like to design / buy an amplifier with the following specs :

Vin = 2.5V (the signal that I put at the input of the amp)
Vout = 10V
freq = 13.56MHz
Rout = 50ohm

Are there IC that basically do this? I was thinking of an amp that has a variable gain that I could adjust maybe with a few resistors. I don't know were to start.

Any idea?

thanks.

Is this sinewave AC with a 10Vpp or 10Vrms output value, or is it digital?

Thanks for your reply,

the signal is a sinwave AC and the values are rms.

thanks.

Your problem is the output voltage, 10 V @ 50 ohms = 2W. This means that a linear class A amplifier will have to run at least 8W DC input power. I do not think there will be an IC that can do this. If this is for fixed frequency then a class B or C amp will do. I would recommend the AARL or the RSGB handbooks for a suitable circuit. The frequency is close to an amateur band (14 MHZ).

A high output current op amp such as one these, may do what you want. Because of the high power output you want, you will need to properly heat sink the device, as indicated in the data sheet, to prevent device failure.
