The Sagetech XP family of Transponders are the smallest in the world and are ideal for small aircraft. Our transponders are an easy choice where size, weight and power are at a premium. The small and lightweight nature of our products gives you more fuel and payload carrying capability and provides greater flight endurance. (General Aviation Transponders, click here)

    The world’s smallest size and weight.  Sagetech Transponders measure just 3.5” x 1.8” x 0.7” and weigh only 100 grams 
     Low power consumption.  Our transponders are a must for power conscious applications 
     Integrated pressure sensor and altitude encoder.  Compliant up to 50,000 feet. The Flight computer can read altitude data
     from the transponder providing backup altitude information.
     Simple integration.  Due to its small size and light weight, the XP family of Transponders minimizes integration complexity
     Plug and Play.  Compatible with most flight computers. Click to view integration partners
