You Have a Filtering Job to Do – We Have the Right Candidate for You

Posted by Dave Thibado on Nov 18, 2020 8:00:00 AM

When designing an RF or microwave application, you will always need some level of filtering to attenuate or remove unwanted signals from the desired channel. Since the end goal of what a filter must accomplish is quite broad, it may seem daunting to know what qualities to look for in a filter to get there.

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.

Achieve Excellent Performance in a Small Footprint with Low-Loss, High Q S and C Band Filters

Posted by Dave Thibado on Oct 28, 2020 8:00:00 AM

At any given time, there are a multitude of signals at a variety of frequencies streaming all around us. This means most RF devices require some level of filtering to attenuate or remove unwanted signals from the desired channel. Without a filter, receiver components can become saturated and unwanted signals can combine with desired signals to corrupt information.

At mmWave Frequencies, Surface Mount Components Are Key to Reducing Cost

Posted by Peter Matthews on Oct 21, 2020 8:45:00 AM

Frequencies in the mmWave spectrum play a key role in 5G communications. RF technology that was developed around existing mmWave applications has evolved to encompass the needs of 5G wireless access and components for such systems need to be selected for performance and cost. Commercial systems are subject to intense price pressure, making both the purchase cost and the implementation cost of a component important factors in selecting devices for a new design. Another key consideration is likely size constraints and the need to preserve valuable board space.

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.
