What 2.4 GHz Power Amplifier Module is so important?
With the development of 2.4G wireless networks, the number of products and users, the more crowded this communication band, in order to improve spectrum utilization, carrier quadrature amplitude modulation (QAM) and quadrature-phase keying (QPSK) and other linearization modulation techniques are widely used.
Which is the linearity and efficiency of the wireless transmitter system requirements are also increasingly high. The quality of the power amplifier peripheral circuit network is particularly important.
With the development of the design and manufacturing process, the quality of the peripheral auxiliary circuit network of the 2.4GHz power amplifier is especially important.
The stability of power supply, high efficiency, low noise output, filtering circuit, impedance matching circuit, and the design of microstrip line in actual production will affect the complete low interference transmission of the signal.
In addition, the integrated circuit and PCB once completed ‘in the actual assembly and production of its own impossible to make changes, but as peripheral auxiliary parts, RLC and other parts can easily do the corresponding adjustments in the spectrum flatness, EVM, and other aspects to achieve the purpose of optimization.
Especially in the field of RF, for the product assembly and production from all aspects of the impact of factors, many of which can not be measured and predicted, the actual measurement of the adjustment of peripheral circuit parameters, has been an indispensable part of the design process.
The output spectrum flatness is directly affected by the performance of the communication channel. For the channel power flatness limit standard, the power of each subcarrier should be between the standard.
And if the power of the subcarriers is too different, the power spectrum is not flat will affect the connection performance. In-band spectrum is not flat, ripple changes a lot, resulting in the fluctuation of the output power, which will accordingly cause instability of the entire RF transmission system.
The causes of the spectrum flatness are a variety of reasons, all levels of parts impedance mismatch signal reflection, the flatness of the parts themselves, from the clock signal multiplier interference, power interference, etc., may affect the output spectrum flatness of good or bad.
Through theoretical derivation and application analysis of 2.4G PA peripheral lines, we summarize the impact of all aspects on the output spectrum flatness and test the improvement of engineering examples to provide the basis for future wireless network design.
