Testing High Rejection Band Pass Filters for High Frequency Devices

August 10, 2022

The rollout of 70 GHz–80 GHz 5G systems and the subsequent need for more E-band devices (like radar sensors) has placed greater importance on using vector network analyzers (VNAs) and their advantages for testing high-frequency components. Many of these active and passive devices will be frequency selectable and include high-rejection components such as duplexers and bandpass filters. VNAs with excellent Spurious Free Dynamic Range (SFDR) measurement capability can characterize and test the out-of-band performance of these high-frequency components during production.
