Hi sir,
I had a research experience of 3 years in designing of RF and Microwave circuits, antennas using ADS, AWR Microwave Office, Ansys HFSS and CST. I had gone through the description given and If I am correct, that Matching network is connected to the RF switch then RF switch is connected to UFL Connector. The matching network should be designed for B3, B5, B8 and B20 LTE, GSM bands.
I will try my best to give you a less lossy matching network as per your specifications. If you need a video while designing the matching network, I will provide that as well sir. I will try to provide a quality work with in a less span of time.
If you are interested let's have an initial discussion through freelancer chat box. I will try to reply you as soon as possible.
Thanks
