Organizing RF and Microwave MMICs into Lettered Frequency Bands and Clarifying Details for RF MMIC Mixers and Multipliers

Posted on Thursday, July 05, 2018

Custom MMIC has organized our MMIC products by lettered frequency bands as a means to help RF system design engineers to quickly narrow-down their choices when reviewing our catalog of high-performance MMICs. With this in mind we would like to state that the frequency band designations we make reference to follow the IEEE standard found below. As mixers operate in different frequency bands depending on the port application, one might consider the RF or LO ports as the frequency in question. For instance, an X-band mixer used in a mil/aero design (for instance as used in RF or microwave upconverter design) systems engineers will likely reference the RF port, where with test and measurement or communications it might be the LO port considered first. Communication systems also tend to use different frequency designations based on different standards, where test and measurement teams often use the nomenclature of what the application is. In addition, we realize that the military, IEEE, and ITU can all have different ways to represent band designations, and region of the world may also matter.

For this reason we adhere to the IEEE standard shown here:

In regards to mixers and multipliers, Custom MMIC has organized our mixers in terms of the RF/LO frequency, and for multipliers, we’ve organized these MMIC designs via their Input Frequnecy or “IF”. If you have any questions, please contact our technical support team.
