Overview
Testing of mobile devices is becoming increasingly more stringent and, as a result, a new test is now being standardized to further
test performance. As this new type of testing, over-the-air (OTA) testing, is developing, an important parameter, Total Radiated
Power (TRP), is becoming increasingly important. Classically, the output power of a power amplifier (PA) has been
measured and evaluated into a 50Ω load impedance; however, the load impedance presented to the PA by the antenna of a
mobile device can vary dramatically in real world applications. The cellular industry has realized that a better evaluation of the
RF performance of a mobile device can be achieved through OTA testing. In regards to the PA, the Delivered Pout Range (DPR)
