Part Number: LMH5401 Out of curiosity, was this ever measured? If not, would you be able to possible provide me with a simulated current (and voltage, if you have it) noise model out to 8 GHz?
Hi Hruday,
thanks for getting back to me on this. I asked this question with a limited understanding of how FDAs actually work. I initially thought I could set up the FDA in the same way as a conventional (single ended) difference amplifier, but after …
Hi Yangang,
The LMH5401 is not stable for unity gain in the standard EVM configuration. However, it can be achieved by few changes. The excel calculator you are referring doesn't account for lower gains. You can follow the below reference design when…
Part Number: LMH5401 Other Parts Discussed in Thread: LMH2110 Hi,
Good Day.
I am trying to understand in LMH5401, what kind of DC gain I am going to get and also what kind of gain I can have if the input is an 8GHz RF signal.
If the input signal is -10dBm…
Part Number: LMH5401 Other Parts Discussed in Thread: LMH3401 , Dear team,
May I know do we have the below data of LMH5401 and LMH3401?
1. Gain vs. Frequency ( from10kHz~10MHz) 2. OP1dB vs. Frequency ( from 10kHz~10MHz)
Thanks.

Hi experts
How are you?
I am trying to design a two stage cascaded amplifiers to get desired gain with 3dB bandwidth of around 800Mhz
LMH5401 is the FDA chosen.
Circuits…

Part Number: LMH5401EVM Hi team,
I have the LMH5401EVM and I am in the process of evaluating this board. I connected it and powered using the single supply and manually grounded the PD pin. Still, I am unable to see the amplified signal. It seems that the…
Part Number: LMH5401 Other Parts Discussed in Thread: TINA-TI Hi,
I tested D/S Fig.57 (Gain4) with TINA-TI. If the output impedance of the differential signal source = 0 ohms, the output will be gain 4. Our customer set the output impedance of the differential…
