10 MHz 2 W (1A/2V) power amplifier
I am designing a power module to drive a transmission coil. I need to drive the coil at 10 MHz and supply 1 A of current at 2V or higher. I am using a crystal oscillator to provide the 10 MHz signal, this gives an output of 1 uA. I need an amplifier that will be modulated by this 1 uA signal and provide me a high Q output at 1 A and 2V. Right now, I have designed for a 5V DC supply, but this can be changed. I have looked at the OPA56x series but I am not sure these will operate at 10 MHz since the plots seem to end just above 10 MHz. Can someone suggest a better chip, or a better solution to my problem? Thanks.
