X Band transreciever module using ads

hello all

i am designing a T/R module in X band for a radar......for this i need a limiter circuit using MA4L011134 PIN diode.......i want to know where can i find .s1p file for this diode......to be used in ADS
Also LNA design using MGF4941AL.......
Also i am designing a 10W Class AB Solid state power amplifier using a discrete transistor whose input power is 20dbm & output should be more than 40dbm at X band.........PAE should be as high as possible..........again i need a transistor not a MMIC!
Can anyone help me to find one? There are some triquint HFETs but shipping problem to my place......
If anyone can upload his/her ads model for above stated devices........
