The microwave diathermy is a heating modality which emits the electromagnetic waves (micro waves) through it.emitter is one of the part of microwave diathermy which on one side is connected to the magnetron through co-axillary cable and on the other side is exposed to the tissues while heating by maintaining certain distance. It consist of an antenna in it.The high frequency generated by the magnetron travels to the emitter through the co-axillary cable.this makes the antenna in it to oscillate with he same frequency. This high frequency oscillation of the antenna then causes the generation of micro wave which is then passed to the surface to be treated.
The emitter can also be changed according to the area to be treated and the type of beam of the microwave that we require.The parabolic type of emitter concentrates the beam, so it can be used while treating small area which requires lot of heating.

What is function of emitter bypass capacitor?
A: THE EMITTER resistor sole function is to provide stability if it is by passed by a capacitor then this resistance will change due to frequency since as frequency increases the impedance decreases. The total gain will change accordingly
What is the purposeof the capacitor between emitter to ground?
The purpose of capacitor between emitter to ground is to permit the transis tor to function in the depletion region without the elimination of the Q point.
What is meant by dependent source?
A dependent source is a source that is dependent on, i.e. a function of, some other thing in the circuit. Often, a transistor is represented as a dependent current source, with collector-emitter current being dependent on base-emitter current times hFe, or beta-gain, limited by the collector-emitter resistor network.
How many doped regions in a Bipolar transistor?
3: emitter, base, collectorThere are three regions but to be absolutely picky I think only two of them need be doped.Nope: they MUST be doped NPN or PNP. If any are undoped it will not function as a transistor.
What is an ir emitter?
Depending on context, it could be an infra-red emitter. An emitter that emits at a wavelength longer than that of visible red. infra red emitter is a special pn juction device in which emitter region emits infrared rays
Why a capacitor is used for amplification in common emitter circuit?
A: The ratio of emitter/collector resistance is the gain. by adding a capacitor on the emitter the AC parameters will shift as a function of frequency
What energy transfer takes place with a microwave?
In a microwave oven, energy is transferred from the emitter (which is technically a klystron) to the water molecules in the item being heated, which have a resonant frequency equal to that of the microwave emission.
How you differentiate base bias and emitter bias?
On the emitter there is base current which is basically a function of Beta and only at that particular current. Unfortunately the beta factor is a non linear function and it is strictly related to collector current
What is function of emitter bypass capacitor?
A: THE EMITTER resistor sole function is to provide stability if it is by passed by a capacitor then this resistance will change due to frequency since as frequency increases the impedance decreases. The total gain will change accordingly
What is the effect on voltage gain in a common emitter amplifier when the decoupling capacitor is removed?
The emitter bypass capacitor, in a typical common emitter configuration, increases gain as a function of frequency, making a high pass filter. Removing the capacitor will remove the gain component due to frequency, and the amplifier will degrade to its DC characteristics.
What is a function of baising?
what is a function of Biasing and explain it's working ? why the Common Emitter Configuration is use as Amplifier ? Explain in Detail ?
What is the function of emitter bypass capacitor in common emitter amplifier?
The emitter bypass capacitor in a common emitter amplifier will have less resistance as the frequency increases. Since gain in this configuration is collector resistance divided by emitter resistance (within limits of hFe), the gain will thus increase for higher frequencies, making this into a high pass filter.
What is the purposeof the capacitor between emitter to ground?
The purpose of capacitor between emitter to ground is to permit the transis tor to function in the depletion region without the elimination of the Q point.
What is the function of a microwave?
to heat up food
Fallout 3 Game Point Lookout what do you do with the reward vault key?
well, you know that bit where you get the microwave emitter, sad to say that is the reward vault.
How do you put microwave in a sentence?
It varys- here are some examples:verb>>>Microwave the covered bowl for 4 min.Noun>>>How do yo use "Microwave" in a sentence?Compare and contrast: Radiowave and Microwave
What would happen if you stuck your head in a microwave?
The water molecules at the spot where the emitter is focused would become excited, eventually vaporizing and cooking the surrounding tissue.
