给你们发个管用的LNA吧！！挺详细的，本人仿真过！

论坛上重复的东西太多了，有些人为了赚币，改个名发很多次，太缺德了，我这个资料论坛上应该没有，即使有的话也很少很少的！本想免费的，可我也需要RD币下载东西的，请大家谅解啊，下完顶一下吧！

The first stage in the design process is to pick a suitable device. For X-Band and above GaAs MESFETS are used while at lower frequencies Bipolar devices are used if noise is not so critical. Try to pick a device design for the range of frequencies you require. Don’t for example use an X-band device for an LNA at UHF – you are bound to run into stability problems. Also pick a device that will give you plenty of gain margin to allow for noise mismatching etc.
For this design an Agilent AT41435 Bipolar transistor has been used. This device has > 14dB of gain at 2GHz with an associated noise figure of <1.7dB.
To double-check the gain available we can use a simple ‘rule-of-thumb’ estimate by evaluating
|S21|/|S12|.
At 1.5GHz this will be 4.63/0.063 = 73.5 or 10*LOG(73.5) = 18.6dB[/COLOR]
