Balancing Linearity and Efficiency in a Power Amplifier

By |2019-04-17T18:49:35+00:00February 14th, 2019|Design Innovation, Uncategorized|

Achieving both high linearity and high efficiency together in a Radio Frequency (RF) Power Amplifier (PA) system is challenging. Typical designs for highly efficient PAs (i.e., greater than 40% DC power efficiency) involve operating devices in their non-linear range, i.e., at or near compression (saturation). A PA operating in its nonlinear region inherently creates distortion [...]

Countering Small Unmanned Aircraft Systems (sUAS)

By |2019-04-22T14:31:37+00:00December 27th, 2018|Product Development|

Once relegated to the skilled thumbs of a hobbyist or teenager with a Styrofoam toy airplane in the backyard, small Unmanned Aircraft Systems (sUAS) have become accessible to a much broader audience. With the advent of brushless electric motors and high energy density lithium batteries, the consumer sUAS market has experienced unprecedented growth. Advances in [...]

What is MIL STD 461 Testing?

By |2019-04-22T15:16:45+00:00December 27th, 2018|Design Innovation, Testing|

The Department of Defense (DoD) purchases a vast array of electronic and electrical devices that must be integrated into various platforms with many other devices and function without degraded performance (electromagnetic susceptibility), and conversely, must function without causing degradation of performance for other devices (electromagnetic emissions). Similarly, electromagnetic interference (EMI) is a commonly used term [...]

Why is RF Filtering so Important?

By |2019-04-22T17:15:42+00:00December 14th, 2018|Design Innovation, RF Filters|

Why is RF filtering so important? Simply put, filters reduce the interference in the environment that affects the performance of the communication system, and reduce the interference caused by the communication system. The lack of RF filtering can affect the performance of the UAS in a number of ways: Communication range is reduced due to [...]

Preparing for the SWARM

By |2019-04-22T17:21:57+00:00October 30th, 2018|Design Innovation|

Like a locust super-swarm in Madagascar, similar to a scene in BBC America’s “Planet Earth II” (image 1), commercial and government programs alike are aiming to employ “swarms” of UAV’s in domestic and overseas operations2. This includes counter-UAS systems, intelligence, surveillance, reconnaissance, near-space and hurricane hunting drones. Swarms of UAVs can be controlled through autonomous [...]

Is Your Project on Schedule?

By |2019-04-22T18:02:00+00:00October 15th, 2018|Leadership Insight|

When working or leading a high technology project, a simple question related to the status of a program can become difficult one to answer. This difficulty is clearly seen by anyone who has been involved in the development, manufacturing and testing high performance radio frequency modules. As with any project, leadership must deal with the [...]

Ball Grid Array (BGA) Mounting

By |2019-04-22T18:07:40+00:00September 12th, 2018|Design Innovation|

Ball grid array (BGA) is a method of surface-mount packaging used for integrated circuits (ICs), whereby the entire bottom surface of the IC is covered with an array of small solder balls to permanently mount devices such as microcontrollers, microprocessors, RAM devices, etc. to printed circuit boards. BGAs support a higher pin count compared to [...]

Weighing the Benefits of Exhibiting at Trade Shows

By |2019-04-22T18:20:31+00:00September 4th, 2018|Product Development|

At some point in time, every company that manufactures a product or provides a service will likely consider whether or not it’s in their best interests to exhibit at industry trade shows.  If you look hard enough, you can probably find an exhibition for just about anything imaginable … from toys to tools to vehicles [...]

Power Amplifiers in Parallel for Higher Output Power – Hybrid Power Combining

By |2019-04-22T18:32:23+00:00August 9th, 2018|Product Development, RF Amplifier|

Recently, we had a customer reach out to us inquiring about a 200 W L-band power amplifier (PA). While we did not have such an amplifier to offer (not yet, anyway), we did have a solution. That solution was four of our new L60T01 amplifiers in a hybrid configuration.   The concept of hybrid or [...]
