2010年11月22日 · Re: IP3 IIP3 P1dB lna rf IP3: Third-order intercept point The intercept point is a purely mathematical concept, and does not correspond to a practically occurring physical power level. In many cases, it lies beyond the damage threshold of the device.

2004年10月8日 · lna ip3 Hi All:) I am designing a high IIP3 LNA.and meet some difficults to imprive IIP3,what should I do? How many methods can be use to improve the LNA's IP3? Thanks!

2014年6月30日 · Dear Sir, I designed low noise amplifier at 1.4 GHz using Avago ATF54143 transistor. I obtained gain of S21 of 17.718dB at 1.4 GHz. Using the template of HB2 power swept in ADS, I have simulated source power, fundamental power, and third order power and using these values , I have...

2020年11月26日 · In order to simulate or measure a OIP3/IIP3 the Output Power for each carrier ought to be approximately -20dB lower than P1dB Compression Point. But your Output level for each tone is Too LOW.

2012年12月14日 · The resulting data display includes pre-configured tables that plot Input TOI (IIP3) and Output TOI (OIP3) for both low side and high side tones. Also fifth order intercept points.

2004年11月24日 · What is the relation between IM3 (3rd order intermodulation component) and IP3 (third-order intercept point)? How do I convert from IM3 to IP3?

2014年8月15日 · In my opinion 34dB difference between P1dB and IIP3 is unusual. This could happen only if the bypass impedance of the bias circuit (at the frequency of F2-F1) is much higher than the input impedance of the LNA. Bias decoupling of both, drain and gate, affect the difference in dB between P1dB and IIP3.

2016年3月20日 · Hi, I've seen a few sources post the following and needed some clarification. Thanks in advance: 1. IIP3=Pin+(Pout-IM3)/2 2. IIP3=Pin+(Pin-IM3)/2 Is #2 valid only if the gain is unity (Pin=Pout)? Or is there something else I'm missing? -Robert

2008年1月17日 · Having a time tough understanding IIP3 (Third Order Intercept Point). I am loking at a radio chip made by Serenza/RFMD that has a IIP3 rating of -15dBm. Does this mean that my input signal to the LNA will be equal to the intermod signal at -15dBm?

2006年11月6日 · The bias bypassing can improve IIP3 performance without increasing current consumption. The impedance of bypassing circuit should be lower than 25% of the input impedance of the transistor at particular frequency spacing, preserving the gain performance of the amplifier. In general any mismatch due to noise matching improves IIP3. Increasing …
