Vishay has expanded its line of ceramic chip antennas with four new small-form-factor, high-performance MLCC devices designed for the reception and transmission of digital signals at frequencies of 868 MHz (VJ5301M868MXBSR and VJ5601M868MXBSR) and 915 MHz (VJ5301M915MXBSR and VJ5601M915MXBSR).
The new Vitramon chip antennas comply with the MBRAI standard for portable communication while maintaining small outlines of 35 x 5 x 1,2 mm (VJ5301M868MXBSR and VJ5301M915MXBSR) and 15,5 x 10,5 x 1,2 mm (VJ5601M868MXBSR and VJ5601M915MXBSR). The devices feature 50 Ω unbalanced tuning interfaces and wide operating temperature ranges from -40°C to +85°C.
The chip antennas are optimised for medical telemetry and instrumentation, industrial automation, security and home automation systems, gas and water meters, remote sensing and control, and long-range RFID. In these applications, the devices help to lower costs by eliminating the need for large external wipe antennas.
