Hey, i found this transistor and it says "I am P120V,3,5A,34W,Ge". My question is how much of this 34W i can get from it without getting it warm ? 8.5W ? This seems unrealistic and strange. Look this transistor is so tiny.. 128861 Bonus question -> how much power i can get with 90W transistor and a big heatsink. 45
Looks like a 12 GHz push-push VCO, having the 2nd harmonic (24 GHz) going to the Divider/PLL.
hi dear all I want to plot a figure like I,ve seen the thread but it does not work for me, it just gives me 3 or 4 arrows with big distance from each other not as the picture so many arrows with short distance. Anybody could help me?
It seems to me that you accidentally activated the magnifying glass tool by Shift+M. To deactivate simply press again Shift+M.
you can do it by setting the DS1307 time format for 12 hour mode as per your picture its looks like you configured it in 24 hour mode. And for display big custom characters first test your all custom char logic by displaying them at same row and column address. if they display correct (...)
You mean a whole 4MB SRAM? By urgent, do you mean your homework is due tomorrow? Because there is very little urgency to yet another simulation of a SRAM cell, in the big picture. It's been done.
the BTA16 is a TRIAC. the simplest approach would be to just replace it. Without a schematic it's impossible to offer any other advice other than to say look at the signal on the triac gate with a scope to see if that looks right.
Hi I am simulating a filter with HFSS 13 driven modal When I mesh at different frequency I have a very big difference in the response Attached is a picture for meshing at 77 and 75GHz Thanks79209
You can also use simple resistor dividers to convert 5V to 3.3V. But this is (same for drivers above) only unidirectional. For bidirectional communication I'd really suggest to use a 3.3V 8051. Not hard to find. Maybe you want to read registers or memory from TFT, e.g. for modifying the picture? Internal memory in TFTs is very big and you (...)
Hi, This looks like motor choke! (Electrical) But tell me the following : You didnt say how big is that motor and that cable. This motor is used for what ? (purpose, what device) Motor works on DC or AC and what voltage ? Do You see clearly that part, is it the same like on Your picture (like solenoid) or (...)
in the pictures are these the big white blocks? if so I only see 2 and not 4. Any advice and help will greatly appreciated. Thanks Francois If you look closer at the last picture you will see the other hiding behind (...)
Helo, i have a flash block from a finepix s1000 camera, and i want to put a simple two wire to power the flash lamp and a switch on/off to charge discharge the lamp/capacitor (it's a big one :) -190uF/330V) and make flashes. I have marked in the attachement picture the damaged zone (...)
hello, I am new to FPGA's, I have a project to complete, could you please help me and explain the overall concept of building an Arcade game using FPGA's. I cannot imagine how graphics is will be displayed. i simply cannot get the big picture. Could you direct me to the links where I can understand (...)
I'm not sure what you are asking but if it is the schematic symbol of this plug use Plug, Phono from the link below Circuit Schematic Symbols the center pin is the signal and the ring is the ground. Alex
However TRAP tends to create a triangular residue at small amplitudes on a lot of nodes, because it is not damped enough. It is less a matter of accuracy, than (excessive and wasteful) activity as all these error residues have to be solved again on the subsequent step ad infinitum. I have yet to see a "big picture" (...)
Usually bondpad is modellled as a big capacitance with only two terminals. Which are the three terminals that you are trying to connect?
Hai everyone...I have problem with my Ultrasonic Radar project.. •the problem is: 1)Motion detector cannot triggered relay. 2)When output from ultrasonic radar not connected to relay,the output voltage is almost 9v when it detect motion. 3)When output from ultrasonic radar connected to r
If regulation is not a big issue you can design very simple voltage regulator based only on a few components such as Zener diode, NPN transistor and resistor .. see attached picture .. Details and discussion is at: Just keep in mind that the output voltage is roughly 0.65V lower than the Zener
the only way of connecting two (or more) voltage sources is to connect them in series .. see attached picture .. Otherwise, the "stronger" one will try to kill the "weaker" one (Kirhoffs laws) and, mate, .. big-bang ... Rgds, IanP
Hi i am trying to simulate a very basic switched capacitor circuit in Virtuoso using a macro op apm model. But when i simulate, as you see in the picture in DC analysis there is very big offset in the output. and in transient analysis there is an error: no DC convergence I think (...)
I'm a biginner of switch power supply circuit. the picture buck.jpg is the top circuit. I want to achieve a 3.3v at vo node. vob node is referenced at 0.5v, and sent into negetive input of error amplifier, and the output of amp is compared with ramp siginal to generate PWM siginal.PWM is sent to driver (...)
I am looking for the air coil inductor between 1uH ~100uH with sustaining 2A and operating until 50MHz(SRF) for power amplifier with MRF136. For this case, I think the chip air coil inductor is not available so I need to purchase the big size wound coil inductor. the picture is (...)
to anyone smarter; I use rabbit RCM3100 microcontroller. i want to control cmos camera (c328-7640). when press a button it will take a picture (in jpeg) and save it to memory. the camera has no motor. it use FTP protocol So what is the big deal? Rabbit produce dev kit for camera. Why don't u grab one and start co
Utilizing spectre simulator and the models file of 5V standard CMOS process , a nmos transistor is simulated, and the DC operation point of this nmos transistor is printed in the picture. Under the condition of normal operation state, i have some doubts concerning its DC parameters: 1. Why is (...)
Hi all, I am new to ASIC synthesis area and have some experience on FPGA synthesis(know most of the detail principle of synthesis). But I don't know the big picture of the synthesis. For example, my friends told me most of user of DC (...)
I had a look at your design. Found two problems: 1. Your lumped port was too big. Look at the picture for a proper lumped port. 2. Your frequency sweep was improperly set for the radiation boundary, since it was 7.5mm from the structure -> solution frequency from 10GHz and above, so for (...)
I don't think, it's easy to get 100mA from the charge pump, capacitors and driving frequency will be too big. Over few milliampers, I would use buck-boost
i am designing a LNA, the first topology of my LNA is as the picture 1, i used the common LC matching network for the output matching of the LNA. When i begin the design of layout, i find this topology has a big problem: the DC collector (...)
1. Banana Jack is where you put you power in (VCC) 2. "Banana Jack" is a Jack. One for Vcc one for GND. 3. the big capacitor is for smoothing Vcc when the circuit takes a lot of current. 4. Dont know, it is not clear from the picture. 5. you put 3 vias. to connect it to the ground (...)
First one would be a non-inverting buffer, but that -15V into +V looks like big trouble. Second one has the same suspicious power supply connection, and now you are jamming 0.5V into the op-amp's output pin. bigger trouble.
Hi, I am a beginner at microcontroller. Now I have a GARMIN GPS 25LVS oem board. I want to show exactly location on a map by an large LCD. Map on the LCD, and it can move. Only a few experience at 89X51 and assambly language. I know the 89X51 is not stong enough to drive the picture LCD. So what do I need to learn? (...)
From my little ignorance..You can't say negative holdtime is a insuffecient parameter but it still have good use like allowing to change the state for a further instance even after a clock so..but the fact the verilog compilers in especially big guns still have a confusing picture (...)
