  • Page 20: Figure 2 - Example Of A Poor Rf Thermal Relief

    Enfora Enabler IIIE Modem Integration Guide For example, a large thermal relief like the one shown in Figure 2 can serve the purpose for general applications such as low current, low speed data lines, DC connections and audio frequency applications. Such thermal relief structures should be avoided for applications where high current and/or high frequency is involved, such as those using the Enabler Module.

  • Page 22: Vbat Input

    Enfora Enabler IIIE Modem Integration Guide If multiple antennas are used in their design, care should be taken during placement selection to minimize the coupling between the GSM antenna and the other antennas. 4.5.1.4. Vbat Input The Enabler Vbat input can have a relative high current draw that can fluctuate rapidly, especially when transmitting at max power and burst mode.

  • Page 23: Figure 5 - Example Of Good Vbat Layout

    Enfora Enabler IIIE Modem Integration Guide Since even the best layout will have some impedance from the source to the Enabler module, sufficient bulk decoupling capacitance is required at the Vbat input to the Enabler module. It is suggested to use at least two 1000 uF, low ESR, tantalum capacitors located very close to the Enabler interface connector Vbat pins.
