In this thesis, we present a module of RF front-end design with low cost, small form
factor and easy integration into LTE module applications. Based on this research, LTE
Band 1, Band 3 and Band 8 are supported.
In LTE Band 1, the measured UE maximum output power at 1.95GHz with QPSK
modulation scheme, 1 Resource Block allocation and 20MHz bandwidth is 23.10dBm.
The measured reference sensitivity level at 2.14GHz with 5MHz bandwidth is
-105.4dBm. In LTE Band 3, the measured UE maximum output power at 1747.5MHz
with QPSK modulation scheme, 1 Resource Block allocation and 20MHz bandwidth
is 23.19dBm. The measured reference sensitivity level at 1842.5MHHz with 1.4MHz
bandwidth is -110.9dBm. In LTE Band 8, the measured UE maximum output power at
897.5MHz with QPSK modulation scheme, 1 Resource Block allocation and 10MHz
bandwidth is 22.95dBm. The measured reference sensitivity level at 942.5MHz with
1.4MHz bandwidth is -112.7dBm.
