In datasheets says that the ADL5606 has GAIN=24.3dB on frequency 2140MHz , but in the table S-parameters on the frequency 2150 MHz S21= 16.9 dB, why so difference? S21 does not mean GAIN?
can anyone help me to figure out what are the specifications of the microstrip lines using as inductors for matching network?
2 questions please:
1) The power down suggests enable is 0V typical - this is not 3V3 logic compatible and suggests a hard pull-down needed to enable?
2) Test have observed a TDD power droop effect and wanted to know if this has been observed by Analogue…
What is the ideal matching network for 2400-2485 mhz band. I want to use 0.8mm/FR4 material.
1、文档给出了1960 2140 2630 3个频率点的匹配电路，包括传输线的长度和匹配电容的容量。 但我根据 TYPICAL SCATTERING PARAMETERS 里面给出的S11 数据 用simth圆图 进行推算后 ，得出的匹配电路与文章给出的3个频率点的匹配电路都不一致。请教这是为何？
2、文档给出的开发板用的是线宽25mil的传输线 板材是IS410 厚度是20mil ，这样我算下来传输阻抗不是50欧姆，文档说是50。请教这是为何？
What's the gain compression curve for ADL5606?
Looking for the current specs on the ADL5604 and ADL5606 when in use. Could only find the quiescent current on the datasheet.
I have some questions about your setup:
For my application with ad-fmcomms1, the transmit power and receive gain are not big enough. When I think of ways to improve the situation, I found the content within the following URL:
