Yagi – antenna
The yagi antenna or yagi-Uda antenna is a high frequency antenna which is used to receive TV signals in very high (VHF) frequency range. It is commonly used in communication when a frequency is above 10MHZ. The
Field effect transistor (FET)
What is mean by FET? FET stands for Field Effect Transistor. The FET is a three terminal unipolar solid state device in which the current is by an electric field as in vacuum tubes. Vacuum tubes are
Satellite communication
What is a satellite communication? A satellite communication is microwave repeater. In satellite communications, signal transferring between the sender and receiver is done with the help of satellite. Collect the information from different sources earth station

Specification of transistor
There are many specification of transistor,some of below: Collector-base voltage (VCB) is the maximum voltage that can be applied across the base and collector of a transistor. Collector-emitter voltage (VCEO) is the maximum that can be applied
RADAR System
RADAR is stands for Radio Detection And Ranging. RADAR system operates in microwave frequencies range. In RADAR system high frequency and high power sinusoidal signals is transmitted. If there is any target then the reflected signals is
Light emitting diode(LED)
The LED stands for a light emitting diode is an optical semiconductor device which emits lights when voltage is applied and it convert the electrical energy into light energy. Just like a p-n junction that can absorb
Difference between PN junction diode and zener diode
