  2. RF front end - Wikipedia

    en.wikipedia.org/wiki/RF_front_end

    In a radio receiver circuit, the RF front end, short for radio frequency front end, is a generic term for all the circuitry between a receiver's antenna input up to and including the mixer stage. [1] It consists of all the components in the receiver that process the signal at the original incoming radio frequency (RF), before it is converted to ...

  3. Elmer FEM solver - Wikipedia

    en.wikipedia.org/wiki/Elmer_FEM_solver

    ElmerGUI – A graphical interface which can be used on an existing mesh to assign physical models, this generates a "case file" which describes the problem to be solved. Does not show the whole ElmerSolver functionality in GUI. ElmerSolver – The numerical solver which performs the finite element calculations, using the mesh and case files.

  4. Topology optimization - Wikipedia

    en.wikipedia.org/wiki/Topology_optimization

    The conventional topology optimization formulation uses a finite element method (FEM) to evaluate the design performance. The design is optimized using either gradient-based mathematical programming techniques such as the optimality criteria algorithm and the method of moving asymptotes or non gradient-based algorithms such as genetic algorithms .

  5. Front-end engineering - Wikipedia

    en.wikipedia.org/wiki/Front-end_engineering

    Front-End Engineering (FEE), or Front-End Engineering Design (FEED), is an engineering design approach used to control project expenses and thoroughly plan a project before a fix bid quote is submitted. [1] It may also be referred to as Pre-project planning (PPP), front-end loading (FEL), feasibility analysis, or early project planning.

  6. Nastran - Wikipedia

    en.wikipedia.org/wiki/Nastran

    NASTRAN was designed from the beginning to consist of several modules. A module is a collection of FORTRAN subroutines designed to perform a specific task—processing model geometry, assembling matrices, applying constraints, solving matrix problems, calculating output quantities, conversing with the database, printing the solution, and so on.

  7. FEM Element - Wikipedia

    en.wikipedia.org/wiki/FEM_Element

    FEM Element is a commercial finite element method solver for electromagnetic structures from EEsof. [1] FEM Element can perform electromagnetic simulation of arbitrarily-shaped, passive three-dimensional structures. It is aimed at providing 3D EM simulation to designers working on RF circuits, MMICs, PC boards, modules, and signal integrity ...

  8. Analog front-end - Wikipedia

    en.wikipedia.org/wiki/Analog_Front-End

    Atheros Intellon 1200 AFE-Chip as companion for an INT 5500 PowerLine-IC. An analog front-end (AFE or analog front-end controller AFEC) is a set of analog signal conditioning circuitry that uses sensitive analog amplifiers, often operational amplifiers, filters, and sometimes application-specific integrated circuits for sensors, radio receivers, and other circuits to provide a configurable and ...

  9. Modal analysis using FEM - Wikipedia

    en.wikipedia.org/wiki/Modal_analysis_using_FEM

    The goal of modal analysis in structural mechanics is to determine the natural mode shapes and frequencies of an object or structure during free vibration.It is common to use the finite element method (FEM) to perform this analysis because, like other calculations using the FEM, the object being analyzed can have arbitrary shape and the results of the calculations are acceptable.
