Continuous Wave (CW) measured power results of the Transmit path (Tx) demonstrates a maximum output power (POUT, Tx) higher than 2W (33.5dBm) with 24% power added efficiency (PAE), and 36dB of insertion gain (GI, Tx) in the 24-31GHz bandwidth. The receiver path (Rx) presents an maximum output power (POUT, Rx) of 30m W (15.5dBm) and an average Noise Figure (NF) of 3.6dB with an associated Insertion Gain (GI, Rx) of 20dB in the same bandwidth. The HPFE/Tx linearity has been investigated with several M-QAM modulation signals with 25/50 and 100MHz channel spacing and using Digital Pre-Distortion (DPD) leading to 48dBc Adjacent Channel Leakage Ratio (ACLR) and 40dB Mean Squared Error (MSE) for average output powers ranging from 17dBm to 25dBm. The linearity performances have been compared to the ones obtained with two other linear GaAs amplifiers (P A1 and P A2) dedicated to point to point telecommunications application: the HPFE presents similar linearity performances associated to a higher efficiency.","PeriodicalId":248339,"journal":{"name":"2018 13th European Microwave Integrated Circuits Conference (EuMIC)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123537564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nitride HEMT technologies are known to reveal a large variety of failure electrical signatures, and it is also largely accepted that multi-tools (multi physics) approaches is the only suitable way to understand the failure mechanisms and to improve the technologies. Experimental stress workbenches usually allow to track a given number of static/dynamic parameters, but specific characterization are only performed at initial and final steps on the devices. This paper proposes a new approach with S-parameters measurement performed during RF stresses without removing the devices under test (in a thermally controlled oven). Then intermediate knowledge of the electrical (small signal) behavior of the devices can be assessed, and crossed with large-signal and static time-dependent signatures.","PeriodicalId":248339,"journal":{"name":"2018 13th European Microwave Integrated Circuits Conference (EuMIC)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128619849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dynamic thermal X-parameter model (DTXM) adds a novel but straightforward method to implement envelope domain sub-circuit in a feedback loop around a conventional static X -parameter model, enabling the simulation of modulated waveform-dependent dynamic self-heating effects. The extended model is identified from conventional CW or pulsed X-parameter measurements, over a range of ambient temperatures. A re-referencing of the extracted X-parameter data to the junction temperature is performed, based on estimated or a calculated thermal resistance and thermal capacitance. The model can also be generated in the simulation environment starting from a dynamic electro-thermal compact time-domain model. The DTXM accounts for thermally-induced asymmetry of intermodulation distortion products and temperature hysteresis depending on the signal bandwidth.","PeriodicalId":248339,"journal":{"name":"2018 13th European Microwave Integrated Circuits Conference (EuMIC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115452076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An efficient systematic searching procedure based on pinch-off and cold weak-forward S-parameters has been developed to consider the asymmetric structure of GaN HFETs and find the optimal values of the gate and drain pad capacitances $C_{pg}$ and $C_{pd}$. Considering that the depletion region extension is varied with the gate bias voltage Vgs slightly even below pinch-off voltage, the obtained initial values of the extracted parameters are optimized by artificial bee colony (ABC) algorithm to improve the reliability of parameter extraction. The developed parameter extraction method shows excellent accuracy and reliability. The proposed procedure can be extended to asymmetric GaN devices with various process technologies.
