Antenna checklist
Two antennas (one connected to
ANT1
pin / connector and one connected to
ANT2
pin / connector)
must be used to support the Down-Link MIMO 2 x 2 radio technology as mandatory feature for LTE
category 3 User Equipments (up to 100 Mb/s DL data rate) designed to operate on Verizon Wireless LTE
3GPP Band 4 / 13 network.
Antenna termination should provide 50
Ω
characteristic impedance with VSWR at least less than 3:1
(recommended 2:1) on operating bands in deployment geographical area.
Follow the recommendations of the antenna producer for correct antenna installation and deployment
(PCB layout and matching circuitry).
Follow the additional guidelines for products marked with the FCC logo (United States only) reported in
chapter 4.2.1
Ensure high and similar efficiency for both the primary (
ANT1
) and the secondary (
ANT2
) antenna.
Ensure high isolation between the primary (
ANT1
) and the secondary (
ANT2
) antenna.
Ensure low Envelope Correlation Coefficient between the primary (
ANT1
) and the secondary (
ANT2
)
antenna: the 3D antenna radiation patterns should have radiation lobes in different directions.
