Notes:

1.

When RF1 and RF2 ports are both open (State 1), all 3 RF ports are terminated to an internal 50 Ω termination

resistor.

2.

When RF1 or RF2 port is open (State 2 or State 3 OFF condition), the open port is connected to an internal

50Ω termination resistor.

3.

When RF1 or RF2 port is closed (State 2 or State 3 ON condition), the closed port is connected to the

RF_COM port.

Unless otherwise noted, the following conditions apply:

•

EVKit loss de-embedded for only insertion loss plots.

•

Vcc = 3.3 V
