SBOS710D October 2014 – February 2018 LMH5401
The LMH5401 is designed to convert single-ended signals to a differential output with high bandwidth and linearity, as shown in Figure 73. The LMH5401 can support DC coupling as well as AC coupling. The LMH5401 is smaller than any balun with low-frequency response and has balance errors that are excellent over a wide frequency range. As shown in Figure 74, the LMH5401 balance error is better than
–40 dBc up to 1 GHz when used with a 5-V supply. Figure 75 plots the input return loss. The s-parameters demonstrate the performance of the configuration, which is comparable (or even better) to a balun.
