These ICs are used quite a lot in ham radio but all of my Googling has failed to find a model, which I wanted to use to understand the little airband scanner that I made.\n\nThe schematic below is based on one in the data sheet. I've also drawn the suggested test circuit and plotted a couple of graphs that feature in the datasheet - and they seem to match *reasonably well*.\n\n## MC1350 Internal Circuit Diagram\n![MC1350_v1](https://github.com/user-attachments/assets/77ce7888-389d-4730-a507-b82d5be7ed81)\n\n##  Power Gain and AGC Test Circuit (10.7MHz)\n![MC1350 test circuit 2](https://github.com/user-attachments/assets/4036d1de-67e7-4f97-b42e-94d1e706ed44)\n\n## Single-Ended Input Admittance I(C1)/V(in)\n![MC1350 Single-Ended Input Admittance](https://github.com/user-attachments/assets/87c2c8c3-2850-4303-86db-da2b638b6b5a)\n\n## Forward Transfer Admittance I(R4)/Vin\n![MC1350 Forward Transfer Admittance](https://github.com/user-attachments/assets/35161001-bdcc-4029-9471-25285748fcd1)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fg1ojs%2Fmc1350-ltspice-model","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fg1ojs%2Fmc1350-ltspice-model","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fg1ojs%2Fmc1350-ltspice-model/lists"}
