Episode 1: Inside RF filter design at ANDREW.
Designing custom RF filters is never about a single component. It starts with customer requirements: frequency bands, insertion loss, rejection levels, power handling. In this episode, our engineer Coco Cao explains how we translate electrical specifications into a complete system-level schematic—sometimes integrating up to ten filters in a single design. From filter type selection to pole-zero synthesis and Q factor definition, this is where performance, size, and cost start to take shape.
