HMC631 - implementation (BALUN)


We are working on an RF Canceller using the HMC631.

The evaluation PCB included a small list of components.

In this list, the Balun, ANAREN BD1722J50100A is employed at the RF input to create balanced 100 ohm input signal.

However, this Balun is not available for us (Digikey, Mousser).

I wondering if you have the same problem?

Do you found  any replace?



  • Hi,

    Any balun with the same impedance ratio can be used in place of the obsoleted balun.

    After quick check, could not find an alternative within same package size **** here are options with different package sizes. Contacting balun manufacturers like Anaren, Johanson, etc. might be helpful.
