Johanson 2.45 GHz RF Chip Antenna Datasheet

VG01 - Item12 - Antenna Datasheet

The 2.45 GHz RF Chip Antenna from Johanson Technology is a miniature ceramic antenna designed for Bluetooth and WLAN applications. Manufactured using Low Temperature Co-fired Ceramic (LTCC) technology, this antenna offers high detuning resilience and stability across extreme temperatures. Its compact SMD, EIA 1206 footprint allows for corner mounting, making it suitable for space-constrained designs.

Key features include an operational frequency range of 2400-2500 MHz, an impedance of 50 Ω, and a return loss of 9.5 dB (Min.). The antenna exhibits a peak gain of 1.5 dBi (Typ.) and an average gain of 0.0 dBi (Typ.), with an average radiated efficiency of 75%. It supports a power capacity of 3W (Max.) and operates within a temperature range of -40 to +125 °C.

The datasheet provides detailed specifications, mounting recommendations, and performance data, including return loss measurements and 2D radiation patterns. It also includes information on tape and reel packaging, as well as orderable part numbers for bulk and tape & reel options. For optimal performance, Johanson Technology recommends following the provided mounting configuration and considering a PCB layout review by their application engineers.
