by Doug Jorgesen A high frequency tone or carrier is defined by two parameters: the magnitude and phase. In many applications it is required to modify the magnitude and phase of a carrier to an [...]
by Jacob Hammond The LO to RF isolation of a mixer is a critical performance specification in most broadband applications. LO feedthrough can not only contaminate a system, but the noise fed from [...]
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 [...]
by Brian Baxter If you attended IMS this year you saw an important product announcement, in a completely new category, from Marki: a switch. A switch doesn’t seem like a big deal, but this switch [...]
by Harley Berman Over the past few weeks, we have spent a considerable amount of time here at Marki Microwave studying the performance of our limiters. Our goal has been to understand how our [...]
By Harley Berman The What and Why of Limiters Limiters are crucial building blocks in Tx/Rx systems and are used to protect sensitive circuity from high power signals. Take for example a simple [...]
By Cameron Sheth In a typical receiver application, a frequency conversion is performed after filtering and low noise amplification. This frequency conversion can have a significant impact on the [...]
