RF Power Amplifier Test Solution
Application Notes
As wireless mobile devices grow in capability and complexity, the associated growth in power demand drives the need for new battery utilization and power efficiency approaches. One of the largest power consumers in a wireless handset is the RF Power Amplifier (PA), so improved efficiency techniques like Envelope Tracking (ET) and Digital Pre-Distortion (DPD) are being increasingly utilized. However, testing these devices with this additional capability can potentially increase test costs and overall time.
This application note will discuss various approaches to maximizing test equipment utilization and reducing test times for such component RF PAs and front-end modules, whether in design, characterization, or manufacturing tests.
