How to extract set of lines from log and store it in file

I have merged 10 logs in to one and I have the following content in each log, I am trying to extract them and put it in a file

****UVM_INFO_PERF FIB-NIB Axix interface per-packet ****
Interface_name = FIB-NIB
Date = 11/11/2020
Interfcae_description = injection
Packet_datarate (bit/clk) = {117,117,118,114,114}

How can I achieve this goal I am trying bash scrip?
