CC1310: Walsin 433Mhz Balun

Scot Cowley

Part Number: CC1310

Hi,

I have been trying to get a hold of someone at Walsin to assist with the CC1310 balun for 433Mhz (RFBLN2520090YC3T10)

I don't receive any responses from the following emails: rexhung@passivecomponent.com info@passivecomponent.com

I was initially looking for layout instructions for the balun - due to the lack of response I decided to just go ahead with a prototype and hopefully someone will respond before the final boards need to be done.

For the prototypes Mouser had around 2000 stock. That depleted in the last week. I can't find any stock and can't get a response from Walsin about this. Do you have any specific contact that I can use besides the above email addresses?

Hi,

Yes, that is the document we used. But it does not go into any details about placement of the component on the PCB (trace lengths, widths etc...).

Please if you could get any useful contact information. The part isn't shown on their website which makes it hard for people to provide support. I am told to contact info@passivecomponent.com but no one every responds. I have emailed multiple times since May 2019.
