A 9 W Low-Cost GaAs MMIC Power Amplifier for C and X Band Communications
The design and measurement results of a 9W MMIC power amplifier, covering the 7.1-8.5GHz frequency range, is described. The PA was fabricated on a mature 0.25um GaAs optically-defined gate process with Enhanced Moisture Ruggedness layer. The PA is assembled in a low-cost 6x6mm QFN package and features integrated ESD protection. In CW mode, the amplifier exhibits 28dB of linear gain and 39.5dBm of saturated output power, with 34% associated efficiency. Optimal thermal design allows for operation up to 105°C. State-of-the-art performance, enhanced reliability, in conjunction with low-cost technologies, make this PA a very attractive option for C/X band communication systems.
