Part Number: LMH5401EVM-CVAL
Hello. We are currently measuring the LMH5401EVM-CVAL. When S21 (Single-Diff) was measured with a network analyzer, 8dB was confirmed according to the data sheet. I want to adjust the power gain from 150kHz to 650MHz to 17dB…

Part Number: LMH5401-SP Other Parts Discussed in Thread: LMH5401EVM-CVAL , Hello, Looking at Figure 78 of the LMH5401-SP datasheet and Figure 33 of LMH5401EVM-CVAL Evaluation Module users guide, the color of PCB pattern near IN- pin is different from other…
Hello KJ,
You should always drive the VOCM pin for the LMH5401; section 8.3.4 of the datasheet should be followed. Please set VOCM pin to 2.5V (mid-supply) externally, you can reference the LMH5401EVM User Guide:

Hello Wyatt,
LMH5401 is a good choice for the application. For the reference design, TIDA-01350, you might have to include feedback capacitors depending on your parasitics + photodiode capacitor on the first stage to compensate for the capacitance the…
Hi Apurva,
I think it would be tough to maintain the maximum voltage of 5.2-5.5Vpp differential in the 1-2GHz range using the LMH5401, as you would start getting into compression issues at these frequencies. I would recommend you to evaluate the LMH5401…
