Hi gurus, Is there some resource on the web I can use to learn
more about the RF development flow? Basically I'm interested in knowing
more about system level analysis using excel or some kind of simulation
tools without getting too detailed into the circuit matching and layout.
Is there any future in doing this? My background is in DSP and wireless
communications simulation. Thanks.

Hello mguo,
The process of designing an RF system usually
starts with a concept of the system. Once you have a clear concept,
then you continue with a block diagram. Each of the building blocks
have its own RF parameters like: Gain, Noise Figure (NF), 3rd Order
Intercept Point (IP3) etc. You cascade the building blocks and assign
to each of them its respective RF parameters. Then you can use an EXCEL
sheet and calculate the cascaded or composite result for each of these
parameters like Cascaded Gain, Cascaded IP3 etc.
As mentioned,
this can be done by EXCEL or by another RF tool like Syscalc etc. This
tools contain the Friis formulas for cascading IP3 and NF.
Hope
this helps!
