Qorvo Uses Keysight's Modulation Distortion Solution to Characterize 5G mm-Wave FEMs

Keysight announced that Qorvo, has used their new Modulation Distortion Analysis test suite to fully characterize 5G mm-Wave front end modules (FEM) performance in production testing.

Qorvo selected the test suite to measure wideband modulated signals and ensure full 3GPP 5G new radio (NR) compliance on all front-end technology up to 43 GHz. This additional production testing capability increases customers' system level yields over the lifetime of a product.

Ensuring reliable and efficient 5G mm-Wave communications requires the performance of integrated circuit (IC) elements to be rigorously tested under linear and nonlinear conditions across the entire workflow from design, validation to manufacturing. Keysight's recently launched modulation distortion application, which is fully integrated with the company's PNA-X Vector Network Analyzer, enables designers of 5G ICs and FEMs to accurately, repeatedly and quickly characterize the behavior of a device under modulated wideband signal stimulus.

According to Kailash Narayanan, Vice President of Keysight's wireless test group, Keysight's collaboration with Qorvo on advanced 5G measurement techniques has contributed to the development of a new approach to evaluating active devices under protocol correct stimulus conditions. Keysight’s suite of IC test solutions with the new modulation distortion analysis application, offers the industry's widest system dynamic range, leading to accurate measurements of parameters such as error vector magnitude (EVM) and adjacent channel leakage ratio (ACLR), which play a significant role in delivering efficient and reliable communications in a 5G network.
