It’s typically expressed as the ratio of stored versus lost energy per oscillation cycle. Steepness of skirts, selectivity, and insertion loss are all specifications that can be described in terms of Q factor. While this FOM feels ubiquitous in RF, truly understanding how Q factor is determined and how it relates to other specifications is a complex endeavor because it’s contextual.  [Read More](https://blog.knowlescapacitors.com/blog/contextualizing-q-factor) 0 Comments [Click here to read/write comments](https://blog.knowlescapacitors.com/blog/contextualizing-q-factor#comments-listing) Topics: [RF and Microwave](https://blog.knowlescapacitors.com/blog/tag/rf-and-microwave) ## [Combining Filter Technologies to Create Higher-Value Compact Filters](https://blog.knowlescapacitors.com/blog/combining-filter-technologies-to-create-higher-value-compact-filters) Posted by [Peter Matthews](https://blog.knowlescapacitors.com/blog/author/peter-matthews) on Nov 21, 2023 8:15:00 AM - [Tweet](https://twitter.com/share) [![Combining Filter Technologies to Create Higher-Value Compact Filters](https://blog.knowlescapacitors.com/hubfs/Combining%20Filter%20technologies.png)](https://blog.knowlescapacitors.com/blog/combining-filter-technologies-to-create-higher-value-compact-filters) There are hundreds of filter applications operating across a wide range of frequencies, which presents a challenge for filter designers since most filter designs don't inherently operate across these wide ranges. Size, weight, power, and cost (SWaP-C) are also important considerations, so simply adding more filters to address different frequency ranges is not an attractive solution. There is, however, an alternative way of designing filters: combining filter technologies to meet the specific frequency, bandwidth, and size requirements of your application.

RF amplifiers are known to cause a non-uniform gain over the operational bandwidth of a device, which results in distortion and other unwanted effects. Equalizers generate a counter-gain profile to offset that uneven response. Pairing equalizers and amplifiers is critical in applications like broadband systems where consistent performance over a wide frequency range enhances signal fidelity and system performance.

In other words, Q factor tells us how good a capacitor is at its job at a certain frequency. A high Q value indicates low energy loss during operation, making these capacitors a good fit for applications requiring low power dissipation and high stability.   [Read More](https://blog.knowlescapacitors.com/blog/high-q-capacitors-roles-and-specifications) 0 Comments [Click here to read/write comments](https://blog.knowlescapacitors.com/blog/high-q-capacitors-roles-and-specifications#comments-listing) Topics: [Capacitor](https://blog.knowlescapacitors.com/blog/tag/capacitor) ## [The Many Jobs of a Capacitor in RF and Microwave](https://blog.knowlescapacitors.com/blog/the-many-jobs-of-a-capacitor-in-rf-and-microwave) Posted by [Peter Matthews](https://blog.knowlescapacitors.com/blog/author/peter-matthews) on Aug 9, 2023 8:00:00 AM - [Tweet](https://twitter.com/share) [![The Many Jobs of a Capacitor in RF and Microwave](https://blog.knowlescapacitors.com/hubfs/Jobs%20of%20Capacitors.png)](https://blog.knowlescapacitors.com/blog/the-many-jobs-of-a-capacitor-in-rf-and-microwave) Radio frequency (RF) and microwave applications involve transmitting and receiving electromagnetic signals at high frequencies. While these terms are often used interchangeably, RF means AC signals at 3 kHz to 300 GHz. For microwave, it’s more like 300 MHz to 300 GHz. [Capacitors](https://blog.knowlescapacitors.com/blog/filter-basics-part-1-a-deep-dive-on-resistance-inductance-and-impedance) play a central role in these applications because they are concerned with capacitance, naturally, and impedance (i.e., resistance), which vary with frequency.

Particularly in radio frequency (RF) and microwave applications, HI-based designs accommodate higher functional density and better performance when implemented with application-specific requirements in mind. Integrated Passive Devices (IPDs), like conductors, resistors, vias, traces, and bridges, play a significant role in HI because they’re largely responsible for the resulting performance optimization when components combine.

Interposers are electronic components designed to sit within a package and connect different circuits and components via interconnects. Thin film interconnects are standard in high-frequency components and subsystems where transmission line widths are small (i.e., .005” and under) to improve overall system performance. They also support high-power applications where thermal conductivity is more of a concern and certain materials like beryllium oxide and aluminum nitride are more commonly used.  [Read More](https://blog.knowlescapacitors.com/blog/leveraging-thin-film-on-ceramic-substrates-for-interconnects-and-interposers) 0 Comments [Click here to read/write comments](https://blog.knowlescapacitors.com/blog/leveraging-thin-film-on-ceramic-substrates-for-interconnects-and-interposers#comments-listing) Topics: [Build to Print](https://blog.knowlescapacitors.com/blog/tag/build-to-print) [Previous](https://blog.knowlescapacitors.com/blog/author/peter-matthews/page/8) [All posts](https://blog.knowlescapacitors.com/blog/all) [Next](https://blog.knowlescapacitors.com/blog/author/peter-matthews/page/10) ## Insights Into Precision Passive Devices Knowles Precision Devices is a premier global source for Capacitors, RF Filters, EMI Filters, Resonators, non-magnetic components and advanced dielectric materials.
