ANT-2.45-CHP-x 2.45GHz ULTRA COMPACT CHIP ANTENNA DATA GUIDE DESCRIPTION The exciting ANT-2.45-CHP is of the one of the world’s smallest, high-performance 2.4 Ghz Chip Antennas. It is ideal for all 2.4GHz applications including Bluetooth, 802.11, home RF, ZigBee and other popular and emerging standards. The antenna uses an advanced multilayer LTCC Technology and a proprietary hybrid spiral element to achieve size and performance characteristics superior to other designs. The incredibly compact SMD package measures a mere 6.5mm (L) x 2.2mm (W) x 1.0mm (H) and is fully compatible with hand- and reflowattachment processes. The antenna's favorable electrical specifications, stability and costeffectiveness make it the logical choice for a wide variety of applications.

A hand-solder temperature of 225° or lower should be used. Do not exceed a 10 sec. heating time. Reflow Temperature Profile The single most critical stage in the automated assembly process is the reflow process. The reflow profile below should be closely followed since excessive temperatures or transport times during reflow will irreparably damage the antennas. Assembly personnel will need to pay careful attention to the oven's profile to insure that it meets the requirements necessary to successfully reflow all components while still meeting the limits mandated by the antennas themselves.
