Dolph Microwave S/X Dual Band Feed System DH-Dualband-Feed-S/Tx&Rx-X/Rx 01 feed is suitable for TT&C applications with S Band Transmit (TX), and X- Band Receive (RX) both in RHCP. It includes corrugated horn, Spetum polarizer, Circular-rectangul transition and diplexer etc. It does not include tracking. Suitable for TT&C applications requiring S- Band transmit and X- Band receive.
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 (Optional)
- Heavy-duty aluminum enclosure, powder coated and assembled with stainless steel fasteners to eliminate external corrosion
- Pressurized feed with temperature and humidity sensors
