difference between RFIC and RF/Microwave circuits - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

What is the difference between RFIC and just plain RF/Microwave circuits? I know one is integrated circuit and one is just more traditional using surface mount(microstrip) etc. But my main question is in what applications do you need RFICs and when do you design just RF circuits.

RFIC -- active and passive devices integrated on chip -- hence the name integrated circuit.

RF/Microwave -- USUALLY discrete using transmission lines, discrete transistors.

I feel no difference.

Obviously the size, but that comes about because of the high dielectric constant used for RFICs. It means a wavelength in the material is physically very short, so elements that should resonate can be tightly packed together in an RFIC. The dielectric constant for typical microwave substrates is 2.2 compared with 10 or 20 for RFICs.

The electric fields are physically constrained by high e materials in RFICs, so circuit element interaction is less of a problem, compared with Microwave stripline circuits, in which layout is crucial to successful design.
