In making the datasheets for the first Microlithic frequency doubler (MLD-1640), it occurred to us that not enough has been made about the difference between isolation and suppression. In mixers [...]

I’ve posted about this before, but there is a persistent myth in the industry that conversion loss ripple comes from bad mixer VSWR. In this post we will dispel that myth. First we start [...]

There are two ways to create high frequency (low phase noise) tones: use a high frequency oscillator to directly synthesize (probably optically) or use a crystal to create a low phase noise [...]

As detailed in our Mixer Basics Primer, the isolations of a mixer refer to how well a balanced mixer cancels out each of the arms inputs from the outputs of the other arms. There are three [...]

In this post we gave a block diagram for how to measure spurs from a microwave mixer. This post is to show some actual data for it. Experimental Setup: I measured an M1-0620NP using two Anritsu [...]
