Hi,

What are the guidelines to be followed in Rf design? Can anybody send the documents & Guidelines reg. RF Design.

Thanks in advance.

Regards

Re: Rf Design

I think razavi book for rf microelectronics is a good start

Hi,

Thanks for the reply.

But In net where could I find the guidelines? Is there any website specifically for RF design? If so Plz tell me the website.

Thanks once again.

Regards,
Suga.

just try the search tool on this BBS,you may get it here if you are lucky enoguh.
 

Re: Rf Design

The best practise in Rf design is to keep the signal trace length as short as possible, provide a proper return path for all RF signals using power/gnd planes. If the circuit is more radiating then you need to provide shielding.

Some more points...

# avoid sharp corners.
# keep signal traces and component leads as short as possible.
# inputs and outputs should be far apart, so that RF energy will not leak back from output to input. stages should line up, rather than snake around.
# decouple the RF parts of the circuit from the DC parts of the circuit.
# shield AF and IF components from RF components.

Re: Rf Design

Hi,

U told to avoid the sharp corners.

What is the advantage for using the smooth corner traces?

Pls explain me more..I'm new for Rf layout design

also avoid splitting those planes under high speed signals
if it necessary use stitching capacitors i.e: capacitor linking the two splitted planes under the signal
