Maybe I was focused to much on finding ADS models for the BLC6G27. MWO simulation data of that type is also included in the AMP_Product_Lib_V14p00.zip
Ampleon answered on my request as follows:
"Regarding your question on the ticket:
please find attached objective data sheet BLC6G27-100. This product never has been released into production. We only produced some small quantity of engineering samples at that time. Products on the market may have a high risk of counterfeit product.
As possible replacement we would recommend BLF7G27LS-100.
