Know Today’s RF Filtering Trends to Better Meet the Needs of Tomorrow’s RF Design Jobs

Posted by Peter Matthews on Nov 4, 2020 8:00:00 AM

At any given time, there are a multitude of signals at a variety of frequencies streaming all around us. Each device that relies on receiving the proper RF signals such as televisions, radios, radars, medical devices, and cell phones, requires some level of filtering. While all filters have the same basic job – remove unwanted or out-of-band signals – the specific job requirements of each filter vary depending on the RF architecture used and the needs of the final device.

The Future of Satellite Communication Design: Four RF Technology Trends You Need to Know

Posted by Tim Brauner on Sep 30, 2020 8:15:00 AM

Over the last four decades, the number of devices that need to maintain mission-critical satellite communications (satcom) has rapidly grown. At the same time, the information transmitted on these devices has become increasingly more complex. As a result, the RF circuit building blocks that make up satcom technology have been through many changes to accommodate the latest advancements in the industry including miniaturization, increased reliability, and the ability to rapidly transmit more complex data.

Let’s explore the following four RF design trends we’ve identified based on our 40-years of expertise in the RF industry that are helping satcom design engineers meet the demands of the many industries relying on their devices today.

High-Reliability Microwave Component Technology Enables Space Innovation

Posted by Peter Matthews on Feb 12, 2020 6:00:00 AM

With more than 2,000 satellites currently orbiting the Earth, and that number expected to quintuple in the next 10 years, the demand for space-ready components is exponentially increasing (Figure 1). At the same time, the technology needed to control and transmit satellite data has changed from mechanically controlled parabolic or dish technology to active electronically steered arrays (AESAs).
