WIN Semis announces mmWave GaN-on-SiC tech
Taiwanese compound semiconductor foundry WIN Semiconductors has expanded its portfolio of RF GaN technologies with the beta release of a robust mmWave GaN on SiC technology.
Core to this platform (called NP12-0B) is a 0.12μm gate RF GaN HEMT technology incorporating multiple refinements to enhance DC and RF ruggedness and add die-level moisture resistance. NP12-0B integrates multiple transistor improvements providing high ruggedness when operated in deep-saturation/high-compression pulsed and CW conditions.
According to WIN, the new technology eliminates the pulse droop behaviour observed in GaN HEMT power amplifiers thereby improving the range and sensitivity of pulsed mode radar systems. Additionally, NP12-0B is available with enhanced moisture ruggedness option and provides excellent humidity resistance when used in plastic packages.
Supporting full MMICs, the NP12-0B platform allows customers to develop compact pulsed or CW saturated power amplifiers for applications through 50GHz. This process is qualified for 28V operation, and in the 29GHz band generates saturated output power of 4.5 watts/mm with 12 dB linear gain and over 40 percent power added efficiency. The NP12-0B technology is ideal for rugged pulsed-mode high power amplifiers used in advanced radar systems.
NP12-0B has reached beta release and is available for early access MPW runs. Qualification testing is complete and final modeling/PDK generation is expected to conclude in August 2024 with full production release scheduled for late Q3 ’24.
WIN Semiconductors will be at the 2024 IEEE MTT-S International Microwave Symposium, in Washington, DC, June 16th through June 21st.
Secure Your Hydrogen Supply
A study supply of high-purity hydrogen is critical to semiconductor fabrication. Supply chain interruptions are challenging manufacturers, leading to production slowdowns and stoppages. On-site hydrogen generation offers a scalable alternative for new and existing fabs, freeing the operator from dependence on delivered gas.Plant managers understand the critical role that hydrogen plays in semiconductor fabrication. That important job includes crystal growth, carrier gas, wafer annealing, and in the emerging Extreme UV Lithography (EUV) that will enable new generations of devices. As the vast need for semiconductors grows across all sectors of world economies, so does the need for high-purity hydrogen.
