Hi,
Can you please share the IIP2 value for ADL5523 LNA?

Hi,our customer designing LNA with ADL5523.For 3.3V power supply,can you help support the S params of ADL5523?
Hello,
Our lab prepare to use ADL5523 to improve the performance fo existing circuits. it works at 433MHz. I have downloaded the ADL5523 s3p file in official website. It is different from s2p, and it use port2(VPOS/VBIAS)to match output impedance. i…
i will monifiy the match network on the ADI ADL5523 evaluation board.
向各位大师求解:
ADL5523的S参数仿真问题。我现在用ADL5523的S参数文件进行ADS的仿真,S参数写的是三端口器件,1端口—RFIN,2端口—bias,
3端口—RFOUT。
现在我仿真如图ADL5523仿真。数据图如图ADL5523数据图;
提问:
(1)仿真时为什么测S(2,1)也有那么高的增益?(2端口不是偏压端口吗?)
(2)我仿真时是不是要测S(3,1)的增益呢?(也就是说3端口就是RFOUT?)
(3)如果2端口是bias端,那么如何连接呢?是不是按照ADL5523文档参考文档来连接电路…
I don't think that we have anything that can match this in a die form factor. For packaged devices, ADL5611, ADL5545 and ADL5523 are the closest matches.
Hi Bruno,
ADL5523 has both poor input and output return loss. When cascaded in series the reflected power cause by the mismatch is likely the cause for the oscillation. You could try to put a attenuator in between the stages to see if you can stabilize…
