Equipment Safety
This product, like all microcontroller products, uses semiconductors that can be
damaged by electrostatic discharge (ESD). When handling, use standard ESD
practices to ensure the transponder is not damaged.
Important:
Whenever power is supplied to the transponder, a 50 ohm load must be provided
to the SMA connection. You can use an antenna or a commercially available 50
ohm load (for example, part number TS180M-10W available from RFMW.com).
XP Transponder Fundamentals
The Sagetech XPC-TR Mode C Transponder interacts with air traffic control (ATC) by transmitting and
receiving standard secondary surveillance radar pulses per ICAO requirements. The transponder replies
to requests from ATC with a squawk code and altitude data. Altitude data can be based on the
t a spo de ’s
integral, calibrated pressure sensor and encoder (termed a
blind encoder
) or one provided
external to the transponder.
The Sagetech XPS-TR Mode S Transponder with ADS-B Out contains all the functionality of the Sagetech
XPC-TR Mode C Transponder. In addition, it provides Mode S replies (includes data such as ICAO
1
address and call sign) and is capable of being selectively interrogated. Also, it adds Automatic
Dependent Surveillance-Broadcast (ADS-B) Out capability. If configured with a GPS data source it can
broadcast aircraft position and other relevant data to the ATC system and surrounding aircraft.
The Sagetech XPG-TR Mode S Transponder with ADS-B Out contains all the functionality of the Sagetech
XPS-TR Mode S Transponder except Mutual Suppression. In addition, the transponder is preconfigured
to use the installed GPS module with an internal GPS Antenna. A connector is provided to enable use of
an optional external antenna as a GPS receiving source.
The Sagetech XPS-TRB Mode S Transponder with ADS-B In/Out contains all the functionality of the
Sagetech XPS-TR Mode S Transponder with ADS-B Out. In addition, it receives ADS-B traffic information
from the ATC system and surrounding aircraft and reports this data to the flight computer, which can
then communicate it to the user. Transponders with ADS-B In are useful for sense and avoid applications
as ADS-B In provides the user with surrounding traffic information within a nominal range of 120
nautical miles (NM).
