Hearing Your Own 6 GHz Carrier in the 4 GHz Receive Chain: Budgeting TX-RX Isolation and Finding the Leak That Broke It

A 6 GHz carrier showing up in a 3.7–4.2 GHz receive chain is not a mystery. It is an isolation budget that came out negative. The uplink and downlink bands are separate allocations — C-band uplink sits at 5.925–6.425 GHz and downlink at 3.7–4.2 GHz (Anritsu, Resolving Interference Issues at Satellite Ground Stations) — so… Read More: Hearing Your Own 6 GHz Carrier in the 4 GHz… »

The ‘Not Friendly Do Not Touch’ Shirt: Reading a Warning Sign as a Boundary Statement

No animal illustration, no pride variant, no decorative frame — just the word, the period, and a lot of dark fabric around it. That scale is the whole argument. A slogan shirt usually works by increasing visual loudness: bigger type, brighter… Read More: The ‘Meh’ Shirt: A Study in Visual Loudness and Dismissive… »

Sizing a BUC for Three Carriers Without Trusting the Datasheet: Pick the Right Figure of Merit First

You have three carriers to put through one BUC. The datasheet gives you a single linear-power number, and the temptation is to subtract a backoff, add a margin, and call the link closed. That number is only meaningful if you know which measurement produced it. For three carriers, the figure of merit that matters is… Read More: Sizing a BUC for Three Carriers Without Trusting the Datasheet:… »
