1. Top 7 Ways to Create a Quadrature (90˚) Phase Shift We’ve talked a lot about IQ mixers in the last few posts, about their theoretical underpinnings and applications as a phase detector and [...]

by Harley Berman   Scattering parameters, also known as s-parameters, are used to characterize the behavior of an RF component to varying input stimuli.  With s-parameters, we can obtain [...]

What is the difference between the BAL line of products (BAL-0003/6/9SMG and BAL-003/6/10) and the equivalent BALH products (BALH-0003/6/9SMG and BALH-0003/6/10)? Which one is a 1:1 (50 Ω single [...]

A while ago we wrote a product feature for Microwave Journal for our isolation baluns. Basically we showed why they were better than 4 port VNAs for high speed differential testing. Check out the [...]

When reading in the literature on the internet about baluns, a distinction that will often come up is ‘current’ baluns vs. ‘voltage’ baluns. I’ve always found this [...]

As detailed in this blog post, there was a previously unaddressed problem with using baluns back to back in a test setup, with a VNA for example. The problem was that the baluns did not have [...]

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 [...]
