Scientific Microwave Corporation, a leading innovator in satellite communication technologies, has introduced its latest advancement, a high-performance K-band circularly polarized receiver (Rx) Satellite Feed Assembly. Designed to optimize signal integrity and polarization accuracy, this product showcases the company’s commitment to supporting reliable and efficient satellite data transmission.
This RX Satellite Feed Assembly operates in the 17.7 to 22.2 GHz frequency range, offering an insertion loss of just 0.6 dB and a Voltage Standing Wave Ratio (VSWR) of 1.30:1. It achieves excellent polarization performance with an axial ratio below 0.6 dB and RHCP/LHCP isolation of 17 dB. Built for durability and efficiency, the assembly supports average power handling up to 650W CW per port and is pressurized to 5.0 psi, ensuring long-term resilience in space applications.
This feed assembly integrates three key components—an Orthomode Transducer (OMT), hybrid couplers, and a corrugated horn antenna. The WR51 E-plane hybrid coupler ensures a 90° phase shift for effective circular polarization. The OMT, constructed with a turnstile junction, provides excellent isolation across a broad frequency spectrum. With dual input ports configured for standard rectangular WR51 waveguides, the assembly enables efficient dual-track reception. Its aluminum 6061 construction, white paint finish, and UG-1530/U and UG-597/U square cover flanges reflect design choices tailored for demanding satellite environments.
Through this launch, Scientific Microwave Corporation emphasizes its ability to deliver technically superior, application-specific satellite products. This RX Feed Assembly offers outstanding performance in polarization purity, low insertion loss, and high power handling, all critical for modern satellite systems. Its meticulous design supports missions requiring high signal clarity and reliability, underscoring its value as a premium satellite component.
The introduction of this K-Band Circularly Polarized RX Feed Assembly sets a benchmark in satellite communication hardware. With its advanced performance metrics, robust construction, and engineering precision, it is well-positioned to meet the evolving demands of space communication systems. This product reflects the Scientific Microwave Corporation’s ongoing pursuit of excellence in satellite technology solutions.
