Directional Couplers

By Kyle Chang As microwave designers push surface mount systems to higher frequencies of operation, the detailed layout of circuitry on a surface mount board becomes more important. This is [...]

Several times per month we are asked about the feasibility of using Marki Microwave products at cryogenic temperatures for various research applications. Many customers have purchased various [...]

Maximum power handling is a common concern of our customers. Nothing is worse than plugging in an expensive device only for it to be immediately destroyed. Understanding power handling is [...]

The most common question we receive about our stripline directional couplers, low loss airline directional couplers, and high directivity directional bridges is ‘How much power can it handle?’. [...]

We’ve talked a lot about IQ mixers in the last few posts, about their theoretical underpinnings and applications as a phase detector and phase modulator. In upcoming posts we will discuss [...]

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 [...]

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 [...]
