    With 5-6 dBm from the Lime you can drive a MHL21336 module to get at least 1 Watt. This is low cost and gives a good signal without much distortions. The module is sold as used device on ebay for around 7€. Just add some cheap passive components and you get a decent amplifier. Check the other posts in this forum, where more details on the construction and data are given.
