This paper reports a package synthesis method in order to ensure good performances in PAE, output power and bandwidth. The internal matching circuits of the optimized package enable to reach the best impedance pre-matching at fundamental frequencies and also to confine the harmonic impedances seen by the internal GaN power bar into safe-efficiency regions whatever the external impedances presented...
This paper presents an internally-matched packaged GaN HEMT for achieving not only high-efficiency and high-power performances but also wide bandwidth and insensitivity to harmonic terminations in S-band. The internal matching circuits of the optimized package enable to reach a wider bandwidth and to confine the harmonic impedances seen by the internal GaN powerbar into high-efficiency regions whatever...
