3.4 eLTE-IoT Module eM300-8a Antenna Design Guide

Users should connect antennas to eM300-8a’s antenna pads through micro-strip line or other types of RF

trace and the trace impedance must be controlled in 50Ω.Reference Design recommends that the total

insert on loss between the antenna pads and antennas should meet the following requirements:

Trace loss

Frequency

loss

902MHz-928MHz

＜0.5dB

To facilitate the antenna tuning and certification test ,a RF connector and an antenna matching circuit should be added.The following figure is the recommended circuit.

Antenna matching circuit（RF_ANT）

In figure ,the componenets R5,C13,C14and C50 or C51 are used for antenna matching. The value of componnets can only be achieved after the antenna tuning and usually provided by antenna vendor.By default,the R5 are 0Ω resistors,and the C13,C14 are 4.7pF，and they are reserved for tuning
