3.5 Solder and Resist Mask

The following requirements must be met:

The Resist Mask should be circumferential 50 µm bigger than the pad size ( 3.3 Land Pattern).

The Solder Mask apertures should have the diameter as the pads ( 3.3 Land Pattern); they are separated in two parts with the shown distance and a shifting.


3 PAN9420 Module


3.6 Placement

Antenna Keep-out Area

Do not place any ground plane under the marked restricted antenna area in any layer! This would be affecting the performance of the chip antenna in a critical manner.


Keep this product away from heat. Heat is the major cause of decreasing the life of these products.

Keep this product away from other high frequency circuits.

The above recommendation for the ground plane is based on a FR4 4-Layer PCB.


3 PAN9420 Module


Impact of Placement on the Antenna Radiation Pattern

The placement of the module, the surrounding material, and the customer components might have an impact on the radiation pattern of the on-board antenna.

It is recommended to verify the perfect position of the module in the target application before fixing the design. In some applications it could be reasonable to use an external antenna to handle application caused placement restrictions.

For the use of an external antenna refer to section 3.8.1 External Antenna.

3.7 Power Supply


The supply voltage must be free of AC ripple voltage (for example from a battery or a low noise regulator output). For noisy supply voltages, provide a decoupling circuit (for example a ferrite in series connection and a bypass capacitor to ground of at least 47 µF directly at the module).

The supply voltage should not be exceedingly high or reversed. It should not carry noise and/or spikes.

Make sure that the power-up sequence meets the requirements mentioned in the PAN9420 Product Specification.

The supply current of VDD (3.3 V) must be limited to maximal 1 A.

3.8 RF Path

3.8.1 External Antenna

Antenna Warning

The PAN9420 is tested with a standard U.FL connector and with the antenna listed in the regulatory and certification chapter of the PAN9420 Product Specification. When integrated into the OEM’s product, these fixed antennas require installation preventing end users from replacing them with non-approved antennas. Any antenna not in the regulatory and certification chapter of the PAN9420 Product Specification must be tested to comply with FCC Section 15.203 for unique antenna connectors and with Section 15.247 for emissions.

The PAN9420 module has a 50  RF pin (SMD pad). Connect an external antenna directly or

via a connector (e.g. U.FL) with RF trace to this RF pin. This RF trace shall be matched to 50 

3.8.2 RF Trace.


3 PAN9420 Module


3.8.2 RF Trace

Ensure that the RF trace impedance is nearly 50 . It is recommended to use a Coplanar

Waveguide with Ground (CPWG) design. The impedance is related to the trace width, the

distances of the trace to the ground layers and the material of the PCB.

The following requirements shall be met:

Trace impedance of 50 

Trace length shall not exceed 2 cm

Via fence around the trace

Crossing no other lines (power supply, interfaces or clock traces)
