Transmitter Spurious Emissions Specifications
The TX spurious emissions specifications in this subsection are based on the following definitions:
• AFE = VCO/16 for 2G channels
• AFE = VCO/18 for 5G 20 MHz channels
• AFE = VCO/9 for 5G 40 MHz channels
• AFE = VCO/6 for 5G 80 MHz channels
• LO = Channel frequency
