first RF circuit design? please help

Hi all I am in the process to choose a RF part circuit to design myself, this is my first time to design chips( I am pretty new in chip design, I learned to use basic use of Pspice very recently), I would like my chip to be manufactured my mosis after I finished design. But I am not sure which kind of part I should choose ( I would like the part can be manufactured by MOSis). Can anyone give me some suggestion which part I should choose? Is it too big to design a transceiver? Actually this is a part of class project(the class project required simulation), but I really want to make it, so if anyone can give me some suggestions, it will be greatly appreciated. My choice for the part is PLL, LNA, Gilbert-cell multipliers, oscillators, transmitters and receivers. It will be great if I can make a transmitters and receivers, I am just afraid if I have can sucessfully make it since this is my first time design. ALso, can anyone give me possible easy-make transmitters and receivers examples, I really appreciate it. I hope someone can help me. Thanks a lot
