Spotlight On Satellite Communications/SatCom/LEO
Small Form Factor SATCOM Solutions

Traditional ground station satellite communication systems in the Ka-band have relied on an indoor-to-outdoor configuration. The outdoor unit includes the antenna and a block down conversion receiver that outputs an analog signal in the L-band.

High-Reliability Microwave Component Technology Enables Space Innovation

Demand for space-ready components is exponentially increasing, and the technology needed to control and transmit satellite data has changed from mechanically controlled parabolic or dish technology to active electronically steered arrays (AESAs).

Internet From The Stars: 21st Century Space Race

SpaceX launched 60 more Starlink satellites into low earth orbit recently, bringing global internet-powering satellites to 180 total. That is far from the planned system completion threshold of 12,000, but it does establish that SpaceX has the formula down.

Benefits Of Foam Polymers In Low-Loss Coaxial Cables

Advancements in high-resolution phased array antenna technology make phase-critical analog and digital transceiver systems reliable in aerospace and defense programs. This paper discusses materials and manufacturing technologies used in these high-throughput data sections. 

Why Satellite Ground Stations Are So Important To Mission Success

Satellite ground stations play an important role in making SATCOM possible by providing real-time communication with satellites and can serve as command and control centers for a satellite network. Simply put, the ground station (or network of stations) is the “brain” of the entire satellite network. 

Industry Insights
The Importance Of GPS (GNSS) Derived Timing

GPS's main function may be to provide a means of deriving position, but the constellation of satellites also is an efficient time keeper. This app note details how GPS or GNSS timing is crucial for critical resource and key infrastructure (CIKR) sectors and stresses maintaining reliable timing networks.

The Importance Of Antenna Beamwidth In RF Testing

Antenna beamwidth determines the expected signal strength given the direction and radiation distance of an antenna. This white paper presents a better understanding of beamwidth, and how it influences a test environment is critical to accurate and repeatable tests.

65 V GaN Transforms The Radar Market: Here’s What It Means For You

65-volt GaN is forging a new generation in radar systems that aim to advance security and monitor a number of commercial applications. This article examines how this technology is transforming radar systems and contributing to this growing area.

NewSpace Terminal Testing Challenges And Considerations

This white paper focuses primarily on the challenges ground terminals (user terminals and gateway terminals) present to design verification testing and manufacturing. Conducted and radiated test solutions are also discussed.

RF Switched Filter Banks

RF switched filter banks have several advantages over separate component designs. These switched filter banks are compact because of the integrated RF filter and switch technology. Another key advantage is improved electrical performance obtained by the combining of technologies. Most often the filter banks are controlled by TTL signals, which is very common in the RF industry.
