How Do RF Filters Really Work in a Satellite Ground Station System?
Your satellite system is plagued by interference, and you think a perfect filter is the answer. But demanding impossible specs wastes time and money, derailing your project before it even starts. An RF filter in a satellite ground station is an electronic component that selects desired signal frequencies and rejects unwanted ones.1 It works like a gatekeeper, using resonant circuits to let your specific satellite channel pass through while blocking all other signals, like noise and interference. As an RF engineer, I often get requests that sound simple but are physically impossible. I once had a client ask me to design a bandpass filter for a satellite project. “I need […]
Becoming an RF Engineer in 2026: Key Skills Needed in the SATCOM Industry.
Are you an RF engineer looking at the booming satellite communications industry? Your current skills might not be enough. A simple module swap from a different field can lead to disaster. To succeed as a SATCOM RF engineer in 2026, you must master satellite-specific skills. These include calculating detailed link budgets1, understanding high-power and high-efficiency amplification2, and designing components that withstand extreme environments3. Simple parameter tweaks from other RF fields are not sufficient for this demanding industry. I learned this the hard way. Early in my career, I tried to use a Low Noise Amplifier (LNA) in a C-band satellite system. This LNA had performed beautifully in Wi-Fi router designs. […]
