4.2 Antenna port test connector

To run conductive RF tests, a test connector nearby the nRF9160 antenna port in the RF transmission line

is needed. The 50 Ω impedance requirement applies also to the test connector, and VSWR and insertion

loss should be minimal. Regardless of whether the nR9160 antenna port is connected to an actual antenna

or test equipment, the load at the nRF9160 antenna should remain as close to 50 Ω as possible.

For a test connector, microwave coaxial switch connectors (for example, Murata MM8130-2600) are a

good choice for this purpose. For conductive tests, a test cable is plugged in which connects the nRF9160

antenna port to the test equipment instead of the antenna. When the test cable is plugged off, the

nRF9160 antenna port is connected to the antenna for real use case or radiated testing. The layout for the

connector must be carefully designed to fulfil the 50 Ω requirement. For detailed guidance on this, see the

coaxial switch connectors datasheets.
