Hi guys, I'm looking for some information about module LPF during the process of making module DAC recently. And I also fell in love with ERICSSON RIFA PBA3244, a product that is almost impossible to purchase in China. I wonder if friends around the world, especially those from Sweden, have detailed photos or related information of this module. I want to purchase him. Thank you again for providing assistance. I am waiting for your message in China. I love DAC modules, but I prefer LPF modules. I think you can help me obtain more information.
