Description
Orbital Dual Band S Band & X Band Tx/Rx Feedhorn is suitable for TT&C applications with S Band Transmit (TX), and X- Band Receive (RX) both in RHCP. The Orbital Dual Band S Band & X Band Tx/Rx Feedhorn incorporates a built in block downconverter to convert the X- Band Receive (RX) signal to a L- Band IF output centered on 1250 MHz.
Orbital Dual Band S Band & X Band Tx/Rx Feedhorn Applications:
- Satellite TT&C operations requiring Transmit in S- Band and Receive in X- Band.
- X- Band RX in RHCP
- X- Band RX to L Band IF output
- S- Band TX in RHCP
Orbital Dual Band S Band & X Band Tx/Rx Feedhorn Features:
- X- Band reception in RHCP
- X- Band septum polarizer for low noise performance and low axial ratio
- S- Band transmission in RHCP
- X- Band Loopback test injection port for testing the complete X Band reception chain
- Two Band coaxial waveguide feed, both bands on axis
- Optional X- Band waveguide filter for radar rejection
- Feed is controlled over the Orbital Data Bus (ODB)
- Integrated low phase noise X- Band block downconverter to L- Band IF output
- Heavy-duty aluminium enclosure, powder coated and assembled with stainless steel fasteners to eliminate external corrosion
- Pressurised feed with temperature and humidity sensors
- Built in purge valve to ventilate the entire antenna when excess humidity is detected in the electrical cabinet or feed

Orbital Systems provides a wide range of antenna feeds for Earth Observation Satellites (EOS) Direct Broadcast (DB), Telemetry, Tracking and Control (TT&C), and general telemetry applications. All Orbital feeds are made of the highest quality materials and are enclosed in a heavy duty aluminium enclosure, powder coated and assembled with stainless steel fasteners to eliminate external corrosion. Orbital feeds are pressurized with temperature and humidity sensors, and built in purge valves to ventilate the feed when excess humidity is detected. STEP Electronics is the Australian and New Zealand distributor of Orbital Systems (now CPI SAT).
