Advantech Wireless’ "Work Horse Wonder" Of 530,000 Hours More Than Doubles MTBF With GaN-based SSPAs 

Field tested, these SSPA's lifespan exceed 520,000 hours of measured Mean Time Between Failure (MTBF), more than twice that of the original calculated MTBF values.

Advantech Wireless newest line of GaN-based Solid State Power Amplifiers (SSPA) have reached unmatched field Mean Time Between Failure (MTBF) operating values. Launched in 2010, and with several thousand units deployed in some of the most stringent environmental applications, the 100-150 Watt line of Ku-Band GaN-based SSPAs from Advantech Wireless has achieved over 520,000 hours of measured field MTBF. 

The corresponding Advantech Wireless 150-250 Watt C-band GaN-based SSPA family of products has exceeded the barrier of 240,000 hours of recorded MTBF. 

These high reliability numbers are more than double of the original calculated MTBF values. Calculated MTBF numbers are based on the individual component’s MTBF values. These methods do not take into consideration any manufacturing or design techniques, so they tend to be inaccurate and establish a minimal expectation of reliability; one that is clearly exceeded by confirmed field experience in harsh conditions in SATCOM installations around the world. 

Advantech Wireless uses an exclusive high temperature burn-in process, temperature cycling, thermal screening, and advanced proprietary design techniques to allow the units to run at optimal conditions and weed out any infant mortality prior to final test and shipment. 

“The wide gap from predicted to field MTBF is due to a state-of-the-art design and continuous improvement of our manufacturing processes,” said Cristi Damian, VP Business Development at Advantech Wireless. “These field MTBF numbers are an assurance of the quality, reliability, and low-cost of ownership involved with operating Advantech Wireless GaN-based SSPAs.”
