输出功率
每个通道上的输出功率可以使用单独的片上检测器进行监测。也可以用温度二极管观察温度。这些传感器馈入多路复用器，该多路复用器将所需信号传送到片上位。还包括用于设备配置和读回的模拟设备端口。尽管状态机提供了最快的状态切换，但也可以通过端口直接控制所有功能。输入缓冲器、×乘法器和带通滤波器。输入缓冲器提供大约的增益，并为×乘法器频带提供最佳驱动器。缓冲器的输入和输出级的偏置电平可通过寄存器通过独立调节。有关更多信息，请参阅偏置点部分。宽带倍频器由三个并联支路组成。
总频率范围
每个子电路（低频带、中频带、高频带）都经过优化，可对总频率范围（.至输入，至输出）的一段进行乘法和滤波。每个频带的推荐范围和寄存器设置如表所示。乘法器块输入和输出处的开关用于选择所需工作频率的子电路。每个子电路由一个×乘法器和一个角频率可调的带通滤波器（）组成。使用寄存器和寄存器，可通过调整×乘法器的偏置水平。有关更多信息，请参阅偏置点部分。当输入频率处于子电路频带的低端时，转角频率必须设置为其低状态。将相关位设置为高，以将角频率设置为低状态。参见表。要完成至的全频率扫描，必须将乘法器滤波器块设置调整七次，以确保最佳谐波抑制和输出功率。
output power
The output power on each channel can be monitored using a separate on-chip detector. The temperature diode can also be used to observe the temperature. These sensors are fed into a multiplexer, which transmits the required signals to the upper chip. It also includes analog device ports for device configuration and read back. Although the state machine provides the fastest state switching, it can also directly control all functions through the port. Input buffer × Multiplier and band-pass filter. The input buffer provides an approximate gain and gives × The multiplier band provides the best driver. The offset levels of the input and output stages of the buffer can be independently adjusted through registers. For more information, see the Offset Point section. The broadband frequency multiplier consists of three parallel branches.
Total frequency range
Each sub circuit (low frequency band, intermediate frequency band, high frequency band) is optimized to multiply and filter a section of the total frequency range (. to input, to output). The recommended range and register settings for each frequency band are shown in the table. The switches at the input and output of the multiplier block are used to select the sub circuits of the desired operating frequency. Each sub circuit consists of a × The multiplier is composed of a band-pass filter () with adjustable angular frequency. Using registers and registers, you can adjust × The offset level of the multiplier. For more information, see the Offset Point section. When the input frequency is at the low end of the sub circuit frequency band, the corner frequency must be set to its low state. Set the correlation bit to high to set the angular frequency to low. See Table. To complete a full frequency scan of to, you must adjust the multiplier filter block settings seven times to ensure optimal harmonic suppression and output power.
