The Frequency Diplexer as a Combiner
Mar 31, 2026 | Engineering Resources
While frequency multiplexers find a great many applications in passive filtering and channelization, the most fundamental of these, the diplexer, is often utilized as a splitter and combiner for MMIC power amplifier chains. Compared to traditional power splitters and combiners, multiplexers split and recombine signals of disparate frequencies, affording lower loss as well as inherent filtering that is not present in their power splitting/combining counterparts. This article discusses suspended substrate diplexers, how they are applied in the Wi-Fi realm, and the merits of their usage in an airborne SATCOM application. Both applications show designs wherein diplexers combine different frequency bands to yield a composite signal at the common port.

Their conversation highlights how Mini-Circuits supports the expanding range of space and satellite applications with Mini-Circuits' program for space upscreening and launch preparation.
The Anti-Parallel Series Pair Limiter Topology
Mar 24, 2026 | Engineering Resources
For more than 6 decades PIN diode limiters have served to enhance the robustness of RF receivers. The anti-parallel configuration is a very popular choice because its insertion loss, recovery time, power handling, flat leakage and frequency response characteristics can be traded off readily by choice of PIN diode. Even increasing the number of PIN diodes utilized in a limiter circuit can affect performance whether they are added in series or in subsequent stages altogether.
