Hi all, i'm a newly man at this forum ,very glad to have the chance to be there with all of you .
and now i've had a confusion about the job of rf design at mobile phone,
it's well known that rf ic is becoming more powerful than ever day by day,
so i though that the job of rf design at mobile is like building toy bricks ,you just conect one module with other module and there are so awful and no interesting. and now i've received offer letter from a telecommution company as rf design at mobile phone, so wish both all of you give me your opinion about the position !
thanks in advance !

Give yourself a chance to explore. If you think it is not suitable for you, you can quit after sometime.

In fact, the mobile design is not simply as you think .
Just because the IC is powerful intergreted, that you want to trim rf circuit is more difficult . So layout of the rf is critical.

You might want to take the job, but don't expect to make a long career out of it. I bailed out of a similar position a couple of years ago because I had build enough products and dealt with enough factory nonsense. The Single chip cell phone is on the way, and you need to have en exit strategy in mind for when you are laid off.

Hi,
many of RFIC wants external RF matching components (there is internally matched RFIC) and this components describes main performance of device (P1dB,Gain,VSWR) this not simply design work and something else very low noise amplifier are on discrete FET.

But the economics of high volume production are driving higher and higher level's of integration. Internal matching is becoming standard, and discrete designs should be all gone, except for legacy production. If you want to do board level RF Design, the mobile phone market place isn't the place to start in, unless you are only thinking short term.
