BU BUCS – WHAT T YOU OU NEED D TO O KNOW! OW! NOVEMBER, 2017
Terrasat Communications IBUC Intelligent Block Upconverters
Terrasat Overview • We make Intelligent BUCs! • That’s all we do - no modems, antennas, hubs, etc. • WE ARE FOCUSED ON MAKING GREAT BUCs! • Founded in 1994 • 55 employees • First to introduce and market “Intelligent” BUC’s • Over 18,000 IBUCs/IBUC2s in service • Manufactured in our modern facility in Morgan Hill, CA • Four worldwide Service Centers
Made in in the USA Every unit is tested over the operating temp range!! Our goal is to deliver our product in 30 days or less. We maintain some stock for next day delivery!
GaAs AND GaN ? • GaAs has been the prevailing technology for decades • GaN use has grown rapidly over the last five years because it allows for smaller, lighter packages GaAs GaN
GaN -WHAT ARE THE CLAIMS/ADVANTAGES? Claimed Advantage Facts True, but varying in linearity. Higher power devices Operate at higher temperature True, but still has to be managed. True. Smaller lighter enclosure High linearity False. Not as linear as GaAs. Low power consumption Becoming true.
POWER RATINGS • Psat – Power at Saturation. A common power rating for BUCs. • However, they are almost never operated at saturation • P1dB – Power at which gain is compressed by 1dB. Commonly used to rate power from GaAs BUCs. • PLin – The maximum linear power as defined by MIL STD 188-164B • This is how GaN BUCs should be rated- The real useable power!
GaAs POWER TRANSFER CURVE
GaN POWER TRANSFER CURVE
OUTPUT POWER CONFUSION Typical Backoff Typical 1-2dB Backoff 3-4dB GaN GaAs WHEN TALKING ABOUT GaN BUCs – USE Plin – USEABLE POWER!
COMPETITOR A – 80 W Ku 4dB difference equates to USEABLE POWER OF 32 W OUCH!
COMPETITOR A2 – 80 W Ku USEABLE POWER = 40 W
COMPETITOR C – 80 W Ku USEABLE POWER = 40 W
TERRASAT – 80W IBUC2G Ku 63 W OF USEABLE POWER !! POW!
LET’S SUMMARIZE • Don’t get GaN Scammed by the competition! • PSAT/P1dB were fine for describing GaAs BUCs, but GaN BUCS need to be rated by Plin • Look for : • BUC Price/ Plin Eq W 80W Psat Ku Terrasat Competitor A Competitor B List Price $ 23,000 $ 22,000 $ 21,000 PSAT 49 49 49 Plin dBm 48 46 45 Equivalent W 63 40 32 $/W $ 365 $ 550 $ 656
