discrete mosfet for class-e rf power design.

I want to design and implement a class-e power amplifier using discrete elements. can anyone help me to find a n-channel mosfet with low Ron (around 100mohms), brakdown dvoltage of 20-30volte and crr (Cgd) of 1pf to operate in 200-250MHz with low input power. Thank you for your favor in advance.
