Directional vs Dual Directional Microwave Couplers
This will be in an upcoming app note, but I couldn’t find a good explanation on the internet of the difference between a directional coupler and a dual directional coupler, so here it is: A [...]
World Record IP3/Linearity Performance
Check out this video: This video demonstrates world record linearity performance. This is a standard two tone test with increasing local oscillator drive power. The device under test is a T3 [...]
Microwave mixers are active devices
One of the misconceptions we frequently encounter is the idea that a mixer is a passive device. Since it has loss and there is no DC bias, it is considered passive unless a gain element is added. [...]
How do signals cancel in a microwave power divider?
On Tuesday, while we were debating over the theoretical explanations of the mega-high linearity T3 Mixer, Ferenc asked me to answer a seemingly very simple question: when you combine two sine [...]
