The Design and Thermal Reliability Analysis of a High-Efficiency K-Band MMIC Medium-Power Amplifier with Multiharmonic Matching

الملخص EN

A new high-efficiency K-band MMIC medium-power amplifier (PA) is designed with multiharmonic matching using GaAs pHEMT process technology.

It has an operation frequency centered at 26 GHz with a bandwidth of 2 GHz.

A 20 dBm 1 dB-compression-point output power and 40% efficiency are achieved.

A novel thermal reliability analysis method based on ICEPAK is proposed also to evaluate its thermal characteristic.

The test result by using a QFI InfraScope™ infrared imaging system is compared with the simulation result.

It agrees well with an accuracy within ±1°C differences, which reflects the advantages of the thermal analysis method with respect to accuracy and convenience for use.
