(iPA) for small form factor and optimum performance. All filters and diplexers will be included in the module to ensure maximum power flatness and optimum VSWR. The module will perform with all legacy hardware having data rates as low as 1Mbps. This chipset also supports concurrent operation of Bluetooth (Version 4.1) for wireless connectivity during browsing or other device applications. Along with both standard and high speed (HS) Bluetooth data rates, Bluetooth low energy modes are also supported. Hardware WAPI acceleration engine, AES, TKIP, WPA and WPA2 are supported to provide the latest security requirement on your network. For placing the SOMAT39 onto the carrier board, the part number to be used is 50145748-001. The footprint details are available in Global Library for using on the carrier board.

Do not run antenna cables directly above or directly below the radio. II. Do not run any high speed digital lines below the radio. III. IV. V. For applications using only 1X1, the second antenna port i.e RF_ANT1 to be terminated with a 50 ohm resistor close to the pin of SOMAT39. Isolate VDD2 & VDD3 (pin no 36 & 37) with a ferrite bead
(BLM15AG100SN1D) and decaps of 22uF and 0.1uF to be placed very close to the pins. 10uF and 0.1uF to be used at VDD1 i.e pin no 23 and the input power supply which are to be placed very close to the pins. VI. A 100K pull down resistors to be used for BT_DEV_WAKE, WL_EN and BT_EN close to the pins of RF SOM. VII. A series R (10E) and shunt capacitor (22pf) is recommended to reduce the SDIO clock noise going to the input of SOMAT39 pin (pin no 43). VIII. Use proper electro-static-discharge (ESD) procedures when installing the SOMAT39 module. 13 Soldering Guidelines SOMAT39 is compatible with industrial standard reflow profile for Pb-free solders. The reflow profile selection to be done based on the thermal mass of the entire populated PCB, heat transfer efficiency of the oven and solder paste used. I. Refer to technical documentations of solder paste for profile configurations. II. Avoid using more than one reflow cycle. III. Aperture size of the stencil should be 1:1 with the pad size. IV. For further recommendation, please refer to the JEDEC/IPC J-STD-020, IPC-SM-782 and IPC 7351 guidelines. Below is the overview of recommended Re-flow:
(1) Solder paste alloy: SAC305 (Sn96.5/Ag3.0/Cu0.5) (Lead Free solder paste.)
(2) A-B. Temp.: 150~200; soak time:60~120sec. (Base on Flux type, reference only)
(3) C. Peak temp: <245
(4) D. Time above 217 : 40~90sec. (Base on SAC305)
(5) Suggestion: Optimal cooling rate is <1/sec. from peak to 217 .
(6) Nine heater zones at least for Reflow equipment.
(7) Nitrogen usage is recommended and be controlled the value less than 1500 ppm. Note: Need to inspect solder joint by X-ray post reflow 14 Chapter 6 Agency Approvals FCC:
