20 / 25 page  20 18.0 Design Considerations 18.1 Antenna Impedance Our OEM modules are intended to be used with a 50–ohm antenna. They are also required to be connected to the antenna by a 50–ohm grounded co–planar waveguide (as shown in the reference design below with the yellow lines) or a microstrip. 18.2 Deep sleep power When selecting a voltage regulator for your application ensure that it has a low power mode, and that this is enabled when the device enters deep sleep. We also recommend cutting off power to all non–essential components such as LEDs, logic gates, sensors etc. when the device is in deep sleep. This can be done using the circuit shown right: This circuit uses the 1.8V output of the module to cut off supply to non–essential circuitry. The 1.8V output is only active when the module is running, when it goes to deep sleep it drops to 0V. The non–essential circuitry is then powered from the “ACTIVE_POWER” bus.
