2.4GHz RF matching development procedure
Figure 7.12
shows the example of the 2.4GHz RF matching circuit configuration. The trap filter is configured to
suppress the higher harmonics close to antenna.
Figure 7.12
Example of 2.4GHz RF matching circuit configuration
This chapter explains 2.4GHz band transmission, reception circuit matching development procedure. 2.4GHz
transmission PA corresponds to 0dBm(1mW) output. The PA is designed to output 0dBm at the 50Ω load impedance
antenna.
