Short answer: not really. Mini-Circuits “DC–22 MHz” parts are fixed, 50 Ω-matched, sealed networks (usually elliptic/Chebyshev LC). To move the cutoff up by ~2 MHz you’d need to reduce the…
You’ve got three good ways to run Linux under Windows 11, depending on how much integration or isolation you want. Here’s a breakdown: 🥇 1. Use WSL 2 (Windows Subsystem…

For 1420 MHz (the H I line at 1420.4058 MHz), the “best” cavity filter depends on where you place it in the chain (pre-LNA vs post-LNA) and what you need…
Good — that’s a nice setup for remotely switching antennas, receivers, or feed chains. Let’s outline how to get both coaxial relays (12 V and 26 V types) under PC…
Ultra-wideband (UWB) cavity filters are specialized RF/microwave filters that maintain the low loss, high power handling, and excellent selectivity of traditional cavity filters, but over a much wider fractional bandwidth…
Short answer: use the quietest DC you can. In practice that means: Why (and how) Hydrogen-line work is extremely sensitive to conducted and radiated hash. Switching PSUs produce combs that…
What is a practical way of generating low resolution images of Milky Way using interferometry with 2 x 150cm dishes at 1420MHz? Following suggested process and Python script comes from…
