Admittedly, it is difficult to teach the concept of electrical flow based on the conventional method that relies on explanation using printed materials. The lack of technology-based materials has made it difficult for students to effectively learn such a concept. Against this background, this study was carried out to design, develop, and test a learning application based on Augmented Reality (AR) called RekBen Tube to help technical and vocational school students in learning the concept of electrical flow. Design: The methods used throughout the production of RekBen Tube application technology education learning tools are the ADDIE Model and the TAM Model. Findings: The actual image depiction of the electric current through the circuit is shown to clearly explain the movement of the electric current. Research limitations: This study has developed an application of 10 flip cards for ...

LNA's design in radio frequency (R.F.) circuit requires the trade-off numerous imperative features' including gain, noise figure (N.F.), bandwidth, stability, sensitivity, power consumption, and complexity. Improvements to the LNA's overall performance should be made to fulfil the worldwide interoperability for microwave access (WiMAX) specifications' prerequisites. The development of front-end receiver, particularly the LNA, is genuinely pivotal for long-distance communications up to 50 km for a particular system with particular requirements. The LNA architecture has recently been designed to concentrate on a single transistor, cascode, or cascade constrained in gain, bandwidth, and noise figure.
