RF Link Budget: How to Match BUC Power with Antenna Size?

Torn between compact antenna size and raw BUC power? That compromise doesn’t just degrade signal—it costs you contracts and cuts into your margins. Matching BUC power with antenna size requires a precise RF link budget. Calculate your required EIRP, factor in the antenna gain (tied to its size), and select a BUC with enough power to overcome path loss, while staying within its linear operating range. I recently had a conversation that many of you might find familiar. A client came to me with a request. “We need to shrink our antenna from 1.2 meters to 0.6 meters to cut costs,” he said. “Can you just tweak some software parameters? […]
