Hello Ramakrishnan,

RM> I  am trying to design a 4702 RF Frontend to hook on my machine. I

RM> simple circuit which can be built?

Check out this page

9v  to  33v  isn't  to far off. At first glance I don't see what would
stop  you  from changing all those D's and C's to a zener and a single
C. Looks like it does about .2mA a bit shy of the 2mA max for the 4702
or  the 4707. Looks like there are a number of chips from Maxim-ic.com
could work fairly well.

Best regards,
