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 the USA

Our goal is to deliver our product in 30 days or less. We maintain some stock for next day delivery!

Every unit is tested over the operating temp range!!

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

Higher power devices True, but varying in linearity.

Operate at higher temperature True, but still has to be managed.

Smaller lighter enclosure True.

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!

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 :

INTELLIGENT BUC VS DUMB BUC

Intelligent BUCs Should be Used When Dumb BUCs Should be Used When

Remote site is hard to access Lowest remote site capex is needed

Site repair visit is expensive Site is easily accessible

Service Level Agreement is in place Extended outage is acceptable

Site commissioning needs to be done trouble free

Onsite or remote support is easily available
