Johanson Technology develops RF and microwave ceramic components using high-frequency ceramic and LTCC technologies. Its product portfolio includes chip antennas, RF capacitors, RF inductors, integrated passive components, filters, baluns, diplexers, couplers, modules, substrates and RF prototyping kits. These components are used to implement compact RF front ends, impedance transformation, filtering, antenna matching and multi-band signal routing in wireless products. Johanson supports technologies including GNSS, cellular, Wi-Fi, Bluetooth and other ISM-band systems, with design resources such as S-parameters and evaluation hardware. A recent development is a compact GNSS diplexer designed to support multiple L-band navigation frequencies including L1, L2 and L5, simplifying multi-band GNSS architectures. Johanson Technology is particularly relevant to RF engineers seeking miniaturized ceramic components and integrated passive networks that reduce component count and PCB area while maintaining controlled high-frequency performance. For RF design, the practical selection process also has to consider operating bands, antenna efficiency or RF gain, impedance matching, coexistence with adjacent radios, cable and connector losses, enclosure materials and the final installation environment. The manufacturer’s development resources are therefore useful during schematic definition, PCB layout, antenna placement, prototype tuning and compliance preparation. Engineers can use the available product families to compare integration level, antenna format, radio interface and environmental requirements while keeping the wireless architecture aligned with the mechanical design. The official manufacturer website provides product-level technical information that can be used to compare available families and identify the most suitable technology for the intended electronic design. For Israeli engineering teams, Boran Technologies can support product identification and local commercial coordination for this manufacturer.
