Looking for resources on microwave mixer design

microwave mixer design

can anyone give me some useful information or links about microwave mixer design. it is to be used for upconversion in an X-band transmitter.

here is a paper

Fundamentals of Active Mixers.pdf

I don't know why it was damaged. Maybe try later.
Here is some link to Gilbert Mixer,maybe they'll be helpful
(you can just search gilbert mixer through google)

Is there any passive mixer?

Re: microwave mixer design

you can find some appnotes on the minicircuits site:
w*w.minicircuits.com

under application notes/ frequency mixers

passive mixer?
Is it possible? for a mixer, you must get a non-linear
behavior, then you should get non-linear R/L/C?
Anyone known of this, please provide docs.
Thanks.

Hi,
Here is a good presentation on fundamentals of active mixers design.
may be this is the one you mean.

Hi,
Passive mixers doesn't mean they are formed of RLC components, it means they are formed of non-linear passive components like diodes, or actve devices (like mosfets and mesfets) which act like switches and not amplification devices. the famous example is the ring modulator ivented many decades ago and it consists of 4 diodes, similar implementations are done nowadays using mosfets. they don't provide conversion gain like active mixers, on the contrary they have conversion loss.

OK, I missed the point.
In fact, I played with the double balanced diode mixer for some time.

So, is the Godz's docs all right. I finally get my doc done.
But it might be same as Godz's because I find the size is just same.
It is by Gilbert from analog.com.

Re: microwave mixer design

Hi,
For those who are interested in mixers design, there is an interesting application note at mini-circuits: www.minicircuits.com/appnote/mixer1-2.pdf . also the attached paper is an excellent one on the fundamentals of monolithic mixers design.
