When Should a Design Consider Using a Custom MMICs

By |2018-05-01T11:43:26+00:00March 9th, 2018|Design Innovation, RF Amplifier|

The continuing drive to improve the Size, Weight, and Power (SWaP) of electronics becomes challenging with consumer-off-the-shelf (COTS) lumped element components since the designers are limited by the physical size of packaged components and limitations of assembly processes.  Moreover, as spectrum congestion forces new systems to move higher in frequency, the performance of radio frequency [...]

Common Applications for Radio Frequency (RF) Filters

By |2018-04-05T19:27:40+00:00December 12th, 2017|Design Innovation, RF Filters, RF Front End|

Radio Frequency (RF) Filters are special circuits that allow a signal of interest to pass through while attenuating any undesired signals.  And while there are a large number of different filter topologies, there are generally 4 filter responses, or shapes, when plotted in the frequency domain.  These four shapes are: Low Pass High Pass Band [...]

How do you keep noise out of RF circuit power supplies?

By |2018-04-05T18:50:23+00:00December 5th, 2017|Design Innovation, RF Filters|

An RF circuit that generates a Radio Frequency (RF) signal, is very sensitive to power supply noise.  If not controlled, the power supply noise can significantly degrade the performance of the system.  So, what are the sources of noise and how can they be addressed? The first potential source of noise is the power source.  [...]

What does MIL-STD-810 certified mean?

By |2018-08-01T14:42:45+00:00October 2nd, 2017|Design Innovation, Testing|

Without additional information, a statement that a product is MIL-STD-810 certified or a requirement that a product be developed to meet MIL-STD-810 does not provide meaningful information about the environmental resiliency of a product.  MIL-STD-810 is a test method standard that defines the environmental test procedures and engineering considerations for the design of a product.  [...]

How can a Low Noise Amplifier improve my system’s performance?

By |2018-08-01T14:41:29+00:00September 28th, 2017|Design Innovation, RF Front End|

From the moment that a modulated Radio Frequency (RF) signal leaves a Power Amplifier and begins its journey to a receiver, the amplitude with respect to the ambient noise starts to decrease.  When the signal arrives at the receiver, it needs to be sufficiently higher than the noise for the receiver to properly demodulate the [...]

When is Power Amplifier Linearity Important?

By |2018-04-05T19:02:01+00:00May 19th, 2017|Design Innovation, RF Amplifier|

In today’s complex world of wireless communications, the radio frequency (RF) power amplifier (PA) provides the final boost in power prior to a signal going out over the air or down a cable. However, choosing the appropriate amplifier for your system can be challenging. While there are many different characteristics of PAs, this blog will [...]
