L-Band Wide Bandwidth High Performance Diplexer, Triplexer, and Quadruplexer

ABSTRACT: MaXentric recognizes that GPS became a ubiquitous global utility, both for civil and military use, the number of digital signals has more than doubled from the original system. The GAM facilitates a flexible navigation payload that is a requirement for the GPS III system, and supports digital waveform generation and potentially new signals. To support flexible signal generation, MaXentric"s n-plexers will support wider bandwidths on the GPS carriers, especially for L1 and L2. The higher signal powers for modernized GPS has increased the risk of multipaction. MaXentric"s solution gives careful consideration to ensure sufficient margin to support even higher power requirements in the future. MaXentric"s GAM will accommodate bandwidths up to 45 MHz, while avoiding multipaction for up to 500 Watts and achieving insertion loss of less than 0.5 dB. BENEFIT: The next generation US Global Positioning System (GPS), the Russian Federation"s GLONASS, the European Galileo, the Chinese Compass, the Japanese QZSS, and the Indian IRNSS, are expected to open a wider range of applications. Such applications will drive the system design toward enhanced resolution, increased accuracy, complete coverage, and extremely high reliability. One of the most significant modifications required by the radio-frequency (RF) payload will be an increased output power, which requires more efficient Power Amplifier. We believe our proposed technology can accommodate bandwidths up to 45 MHz, while avoiding multipaction for up to 500 Watts and achieving insertion loss of less than 0.5 dB. In order to test the product and move the proposed solution to commercialization, MaXentric will capitalize on our existing relationships with the major Prime Contractors and other commercial partners.
