1KW Mosfet FM Amplifier Service and Operating Manual
2008-07-01 18:08:00 High gain MOSFET transistors and systematic use of state-of-the-art manufacturing methods, have helped us to find effective solutions for the design of this new equipment. The amplifier, of simple and rugged construction, is able to satisfy the requests of all those end-users looking for top-quality equipment at reasonable prices. The RF power input is divided by 4 by means of a power splitter and is then connected to 4 x BLF278 MOSFETs.The power amplifier is lightweight with broad-band characteristics over the entire VHF FM range. The compact design and the internal configuration of the modules, allow excellent access to all components. All the power components are generously over-rated to ensure excellent reliability. The cooling system of the equipment makes possible to keep all components which dissipate heat, at low temperature figures, thus permitting reliability and very high MTBF.1 KW Power Amplifier Module The input power of the module is connected to a Wilkinson splitter, ...
MOSFET inverter
2008-03-26 04:13:00 i have an assignment regarding the modelling the MOSFET inverter circuit using MATLAB 7. My lecturer wanted to see the output of that model in a rectangular waveform. is there any suggestion for my assignment?? i want to do by using the simulink model but i'm still a beginner in MATLAB software.

FET Power Amplifiers - MOSFET Output Power Amplifier
2008-01-14 04:38:00 Although there are a few, all MOSFET power amplifiers are uncommon. Most use a combination of bipolar transistors (for the input and gain stages), and MOSFETs for the output devices. This seems to be the most popular circuit arrangement, so I will concentrate on this. Figure below shows a fairly typical arrangement ...
FET Power Amplifiers - Single Ended MOSFET Class-A Amplifier
2008-01-12 04:27:00 In exactly the same way as a power valve can be used in single-ended Class-A, so too can a MOSFET. A simple circuit is shown in Figure below which will provide about 10W of audio. Using a constant current source as a load (as shown) gives much better efficiency than a resistor, ...
FET Current Amplifier
2008-01-11 04:21:00 Again, I have shown both a junction FET and a MOSFET in Figure 3.3, both common-drain or source-follower circuits. As can be seen, the junction FET is biased almost identically to a valve, but all voltages are much lower. The MOSFET requires a positive voltage, and this must be greater than ...
Field Effect Transistors and MOSFETs
2008-01-10 03:45:00 Now on to FETs and MOSFETs. FET stands for Field Effect Transistor, and MOSFET means Metal Oxide Semiconductor Field Effect Transistor. This topic is something of a can of worms, not because of some deficiency in the devices, but because of the huge array of different types. The basic FET types are N-Channel ...
Connecting PWM Signal to 3-Phase MOSFET in MATLAB Simulink?
2008-01-08 13:33:00 I am having a problem connecting PWM waveform as signal to the gate of MOSFET. It is a 3-phase inverters circuit which combines of 6 MOSFETs. So, in MATLAB simulink, how do I obtain PWM waveform and feed it to the MOSFETs? thank you.
Wanted: SiC Power MOSFETs
2007-11-07 09:25:00 Hi all, SiC-power-diodes for high voltages (1200V) and up to 50A are comercially available meanwhile from companies like CREE, but who knows a deliverable source for SiC-MOSFETS of that rating (600 - 1200V, ~20A or more) ? We think of using these devices on PCB or hybrid,
Basic MOSFET amplifier 100W with 2SK1530,2SJ201
2007-09-02 18:30:00 Intro detail: I propose you here a basic MOSFET amplifier. Output power is +/- 100 Wrms under 8 ohms or +/- 160 Wrms under 4 ohms. Due to the circuit simplicity, distortion is +/- 0.1 %. Bandwidth at -3 db is from 4 Hz to 96 Khz, it is limited by C1, R1, C2 and R2. Transistors T1 ...
12VDC Fluorescent Lamp Inverter with Mosfet
2007-08-26 09:22:00 It uses a normal 120 to 6V stepdown transformer in reverse to step 12V to about 350V to drive a lamp without the need to warm the filaments. Q1 must be installed on a heat sink. A 240V to 10V transformer will work better then the one in the parts list. The problem is that they ...

2007-07-30 03:34:00 The picture above shows a circuit board layout giving every option that the MOSFET amplifier will use. This board could be built very easily using “Manhattan Construction” or “dead bug” style construction. I have also built it on mass produced prototype boards from Tanner Electronics. Radio Shack and others have similar ...
AGC Amplifier by mosfet
2007-07-30 03:32:00 This amplifier does not have AGC applied. Two 100K resistors are used to set the gate 2 bias at approximately six volts, bypassed with a .01 decoupling capacitor. This amplifier may have a tendency to oscillate, if so, detune the 455 kHz IF can or add a resistor of 2.2K to 12K across ...

Practical Mosfet Testing for Audio
2007-07-14 09:35:00 First off, a Mosfet is an electronic amplifying device, more specifically, a transistor. It is a little part that has three connecting pins coming out of it, known descriptively as the Source, the Drain, and the Gate. Using a hydraulic metaphor, if you think of the Mosfet as a faucet, then the Source and Drain are what the water flow through, and the Gate is the lever that turns the flow on or off, fast or slow. Except, of course, that the water is electrons, and the lever is operated by electronic charge.
