2.4.1 Noisy signals

Keep potentially noisy traces and components of the motherboard as far as possible from

the antenna to prevent dispense of the module.

3 Power supply for ICC-A-1

3.1 Regulated power supply

ICC-A-1 can be supplied from a regulated power supply down to 2.1 V in all conditions.

During peak load transients, power supply can be up to 100mA when using high power

mode. The product designer shall verify unconditional stability during peak load to

secure that voltage is not dropping below 2.1V.

The actual design of the regulator affects the decoupling capacity. Make sure that no

noise is injected via the power supply that can impact the analogue parts of the radio.

3.2 Coin cell battery operation

ICC-A-1 can be operated from a single 3.0V coin cell battery. A minimum of sustaining

2.1V during all peak transients until battery end of life is required to guarantee proper

operation.

Make sure to fulfil the below requirements:

• Add enough decoupling to the device to avoid brown out during transient load in

TX burst. 20uF < 200uF.
