  • 5G/4G Combined Antenna Analysis in a Smartphone using EM Simulation
    A proposed smartphone design that includes a 4G antenna operating at 860 MHz and a 5G array at 28 GHz is analyzed in XFdtd to determine operating characteristics and any mutual coupling. A brief study of configurations is performed to find the best positioning for each antenna.
  • Things You Need to Know About Combiner and Duplexer
    In the wireless mobile phone communication system, the main function of the combiner is to combine the input multi-band signals and output them to the same indoor distribution system. The combiner is generally used at the transmitting end. Its function is to combine two or more radio frequency
  • Wearable Dual-Band MIMO Antenna Simulation
    This simulation of a wearable dual-band MIMO antenna demonstrates a design for dual-band use constructed of textile materials. The performance of the antenna remains acceptable as it is deformed. When combined in a MIMO array, the antennas show good isolation and acceptable antenna performance.
  • AA-Series Field Generating Systems
    and antenna combined in a single housing, which can then be paired with a rack-mountable power and RF routing unit.
  • Krytar 180 Degree Hybrids. Control Signals from 1 to 26.5 GHz (.pdf)
    Hybrid Couplers perform many functions, including splitting and combining signals in amplifiers, switching circuits, and antenna beam-forming networks.
  • Krytar 3 dB 90 Degree Hybrids. Covers 0.5 - 40 GHz (.pdf)
    90 degree hybrids are used in circuits requiring a balanced division of power into two transmission lines with 90 degree separation of phase. Applications include signal splitters, combiners, balanced mixers, imagerejection mixers, phase shifters, diplexers, switches and antenna feed networks.
  • 90 & 180 Degree Hybrid Coupler Primer
    Hybrid Couplers are passive devices used to perform many functions, including splitting and combining signals in amplifiers, switching circuits, and antenna beam-forming networks used in a wide range of commercial and military applications where power or frequency needs to be monitored, leveled
  • CobaltFx System Anchored by the Cobalt C4209 4-port 9 GHz VNA Delivers Accurate and Repeatable mmWave Measurements
    Copper Mountain Technologies' CobaltFx frequency extension system has given Anthony Macari and the team at Pacific Antenna Systems (PAS) the ability to make accurate and stable mmWave measurements for various antenna types. PAS uses a CobaltFx system anchored by the Cobalt C4209 4-port 9 GHz VNA
