5. Typical Applications and Connections

5.1 RF Connections

5.1.1 Antenna Ports

The WGM160P offers two RF ports that support antenna diversity using an internal switch. In applications with only one antenna, the

unused port should be terminated to ground with a 47-51 Ω resistor. Leaving the unused port floating or tying directly to ground will

result in degraded performance. An external antenna connected to either RF port needs to be properly matched with at least -10dB

return loss (VSWR < 2).

5.1.2 Antenna Diversity

In applications where multipath fading is a potential issue, such as indoors, a second antenna can be connected. A firmware feature

can be enabled to automatically determine which of the two antennas gives a better signal, allowing significant improvement in link reli-

ability.

5.2 Multi-Protocol Co-Existance

Packet Transmit Arbitration (PTA) pins are provide to share antenna and optimize co-existence performance with other networks includ-

ing other protocols. See Application Notes "AN1128 Bluetooth Coexistance with Wi-Fi" and "AN1017 Zigbee and Thread Coexistance

with Wi-Fi" for more information.
