A 2.5 Watt 3.3-3.9 GHz Power Amplifier for WiMAX Applications using a GaN HEMT in a Small Surface-Mount Package

A 2.5 Watt 3.3-3.9 GHz Power Amplifier for WiMAX Applications using a GaN HEMT in a Small Surface-Mount Package

A 2.5 watt average power (15 watt peak power) amplifier for application with WiMAX signal protocols has been constructed using small surface-mount GaN HEMT transistors. The GaN HEMT characteristics are uniquely suitable for producing high peak power in very small (3times3 mm) surface-mount packages....

Zusammenfassung:A 2.5 watt average power (15 watt peak power) amplifier for application with WiMAX signal protocols has been constructed using small surface-mount GaN HEMT transistors. The GaN HEMT characteristics are uniquely suitable for producing high peak power in very small (3times3 mm) surface-mount packages. The PA produces 12.5 dB of gain over 3.3-3.9 GHz, with EVM under 2.5% with 2.5 watts average output. A design methodology for optimizing performance for the WiMAX protocol is presented.
