  Hello Ash, Unfortunately, a frequency at 6GHz will be difficult to achieve with this setup. Even if we are able to get 6GHz for each 2-4V/V gain stage, at later stages in the design this will not follow a small signal frequency response plot, but the…

• LMH5401: Cascading amplifiers

  

  Ash LAW

  Part Number: LMH5401 I need to cascade 2 or 3 LMH5401 amps to get the amount of gain needed. However both a board and a simulation using the TI spice model show a roll off well below the desired 6 GHz level if multiple LMH5401's are cascaded. Each 5401…

• LMH5401: TIA LMH5401 and amplifier (2 steps)

  

  HW_007

  Part Number: LMH5401 Hi! We need to do a TIA for space application. The first step is done with a commercial amplifier (LMH5401). For that, I use two; one of this is used like TIA (with input +-5uA with 400MHz) and the output is more or less +-2.6mV…
