High-VSWR Tuners Ease Device Matching To 6 GHz

摘要

Load-pull tuning systems provide tremendous insight into high-frequency devices under variable-impedance conditions. In terms of device and component optimization, for example, a load-pull tuner makes it possible to find the impedance-matching conditions for optimum transistor or amplifier output power or efficiency, of particular importance in the increasingly competitive wireless equipment market. The new, patent-pending High-Gamma-Tuner™ (HGT™) system from Maury Microwave (www.maurymw.com) brings a new dimension to load-pull testing by allowing for the first time direct on-wafer GSM/EDGE load-pull measurements at RF output power levels to +35 dBm. Coupled with the tuners'' wide VSWR (reflection) range and low loss, the automated tuner systems help reduce modeling and process uncertainties and cut process development time for RF power transistors, amplifiers, and modules at frequencies from 825 MHz to 6 GHz.
