I am currently being developed for LTE RF Power amplifier.
The specifications are as follows.
Output Power: 35dBm
Frequency band: 728 ~ 757MHz
Test signal: 10MHz band OFDMA
RF Power amp in the 3GPP TS361.141 V91.0 Operating band unwanted emission limits must be met.
However, Table 9.1.5.3-3: Additional operating band unwanted emission limits for E-UTRA (bands 12,13,14 and 17) can not understand.
The definition is as follows.
input signal bandwidth: ALL
Frequency offset of measurement filter-3dB point. delta f
: 0MHz <delta f <100KHz
Frequency offset of measurement filter centre frequency, f_offset
: 0.015MHz <f_offset <0.085MHz
Test requirement-13dBm
Measurement bandwidth 30KHz
Here, signal bandwidth is a 10MHz
Spurious Emission of 0MHz ~ 100KHz offset can not measure?
I also do not know of Table 9.2.5.3-3.
The definition is as follows.
Operating band 13
Frequency range: 763 ~ 775MHz
Maximum Level:-46Bm
Measurement bandwidth: 6.25KHz
The amplifier's performance in the above definition possible?
