Part Number: LMH5401 Other Parts Discussed in Thread: ADC12DL3200 , Tool/software: Hi,
I am using LMH5401 to drive inputs at ADC12DL3200. LMH5401 gets differential inputs from a demodulator. Below is the circuit being used
Demodulator Output will have…
Part Number: LMH5401 Tool/software: The circuit when we use LMH5401 are as follow picture
We built a model in ADS for simulation of this usage. The model of LMH5401 is achieved from the official website. The models of PCB wiring and coaxial lines a…
Part Number: LMH5401 I have read the note: Differential to single-ended: What happens when you use only one differential amplifier output
and I am ok with no common mode rejection and losing 3dB gain and the harmonic is not the primary goal.
But when…
Part Number: LMH5401 Hello
Please let let me know if the LMH5401 has been characterized for Rf = 1K or 2K.
What will be the 3db bandwidth at G =1 and or g = 5?
Will a compensating Cf need to be added?
Hi Michael, sorry for the delay in response. I have updated my simulation to include the PD capacitance and trace capacitance. I am using a 0.9pF FB capacitor to improve stability, calculated using a TI app note. Running the AC analysis shows instability…
Part Number: LMH5401 How much do you expect the CMRR to change vs. temperature/Rload/gain? I'm designing a circuit with tight CMRR specifications,and wanted to get an idea of how much variation I should expect to have.
Thank you!
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?
