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 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?
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…
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?
