Radio frequency is a sub-branch of electrical and electronics engineering. It is a diversified field that revolves around the wireless transmission of radio waves between multiple electronic devices. Radio frequency engineers specialize in transmitting and receiving of waves through wireless devices.
IEEE and WCET are two governing bodies that regulate the radio frequency engineering at various levels. Both these bodies also issue certifications to RF engineers in multiple domains. There are various advantages that RF engineering has to offer. Cellular mobile services, television, and radio transmission are done through RF engineering. The application of RF engineering is restricted at all. RF engineering is applicable in a diverse range of industries like medical instruments and appliances. Similarly, RF engineering has a role to play in radar and satellite communication as well. RF engineering concepts are used as a basis in signal communications.
RF engineering concept largely based upon mathematics and physics principles. RF engineering can yield quality results in terms of general electronic concepts. RF engineers are specialized in as wave propagation, impedance transformations, filters, and microstrip printed circuit board design. RF engineering has continued to provide a driving force for many applications in domestic and commercial sectors. RF engineering is fast and reliable. The expansion of the telecommunication industry is because of cutting-edge startup delivering technology used by RF engineering designs.Assumi Radio Frequency Engineers
The attached transmit circuit has very high S11 (and VSWR) at frequencies below 100 MHz. Adjust the values of the L,C shown in the shematic so that it has low VSWR (less than 1.3) and low S11 for the frequencies 60,70,80 MHz. The needed parameters are: 1. The output impedance at TX1_1 must be 50 ohms. 2. Transmit analogue input impedance 40 ohms 3. Transmit load impedance at the output pins 400 o...
