SPECIFICATION Part No. : SGGP.25.2.A.02 Description : GPS/GLONASS/GALILEO SMD Mount Embedded Ceramic Patch Antenna 25*25*2mm Features : 3.34 dBi Peak Gain for GPS/GALILEO Band 3.32 dBi Peak Gain for GLONASS Band 25mm*25mm*2mm dimension SMD direct mount ceramic patch antenna Automotive TS16949 Production and Quality Approved RoHS compliant Front Back DSP-15-8- SPE-16-8-080/A/SS Page 1 of 16 1. Introduction The SGGP.25.2.A.02 is an embedded SMD ceramic GPS/GLONASS/GALILEO passive patch antenna with a low profile of 2mm thickness. It is designed for applications such as - navigation - infotainment - vehicle tracking/fleet management systems - UAV - telematics devices where a high performance solution is needed in a low profile form factor The antenna has been tuned to mount centrally a 50*50 mm ground plane, working at 1575.42MHz and 1602MHz, with a 3.34 dBi gain and 3.32 dBi gain, respectively. 70% efficiency is best in class. The ceramic patch is mounted via reflow process from a pick and place machine. The antenna itself is manufactured and tested in a TS16949 first tier automotive approved facility. For further optimization to customer specific device environments where ground-plane size or mounting location is different, which can lead to detuning, a custom tuned patch antennas can be supplied, subject to NRE and MOQ.

Recommended Reflow Soldering Profile SGGP.12 can be assembled following Pb-free assembly. According to the Standard IPC/JEDEC J-STD-020C, the temperature profile suggested is as follows: Phase Profile Features Pb-Free Assembly (SnAgCu) PREHEAT Temperature Min(Tsmin) 150°C Temperature Max(Tsmax) 200°C Time(ts) from (Tsmin to Tsmax) 60-120 seconds RAMP-UP Avg. Ramp-up Rate (Tsmax to TP) 3°C/second(max) REFLOW Temperature(TL) 217°C Total Time above TL (tL) 30-100 seconds Temperature(TP) 260°C Time(tp) 2-5 seconds Rate 3°C/second(max) PEAK RAMP-DOWN Time from 25°C to Peak Temperature 8 minutes max. Composition of solder paste 96.5Sn/3Ag/0.5Cu Solder Paste Model SHENMAO PF606-P26 Soldering Iron condition: Soldering iron temperature 270°C±10°C. Apply preheating at 120°C for 2-3 minutes. Finish soldering for each terminal within 3 seconds, if soldering iron temperature over 270°C±10°C for 3 seconds, it may cause component surface peeling or damage.
