How to isolate the receiver and transmitter block in RF transceiver IC design?

hi,everyone
I want to design RF-fornt IC tranceiver for wirless communication, traditionally, but how to isolation the receiver and transimitter block, any process constrains? such as STI?

thanks

go search for google ..and u will get the good stuff..

typically to isolate them , u need to used duplexer
or u need to isolate them on chip

khouly

If you are talking about the isolation on silicon, you have to put them farther way in the layout.

yes, As is known, the receiver and transmitter end must be isolated effectively, and in order to do the sigle chip integration of RF-front end and baseband, I want to design the tranceiver front-end by TSMC or SMIC 0.18 RFCMOS or Normal-CMOS process, but how to understand the process relationship with this type RFIC? and how to select?

thanks
