This shows how to do it with the ver. 4 device. Should be similar. http://www.ezoflash.com/willem_info/files/eprom.htm

no schematic?

I used a amplifier based on the PA0RDT "Mini-Whip" because of it's low input impedance and low noise floor. You might be able to get away with just using the J-FET input stage and feeding the output

Unless the input signal goes below ground, to a negative voltage, this IC is very tolerant of noisy signals with no ringing or overshoot. A 1k or even a 10k resistor certainly won't hurt the

what buffer amp do i need to connect my sdr to my yaesu ft-707 to use it as a panadaptor,i am looking for a cct diagram so i can homebrew something,thanks.

Looking at the data sheet it can be operated with a Vcc up to 5.5 VDC, max.? You may also need a series resistor at the output pin to reduce/eliminate ringing/overshoot/undershoot on the signal

The SN74LVC1G17 is rated to ~100MHz, most will work up to at least 150MHz. Operation is simple, feed you sloppy signal in and get a clean signal out with extremely sharp transitions, it won't be a

To emulate a regulator failure, I use a LM317/338 with a suitable diode between it and the load, I adjust the LM317 for 0.7V higher then the design goal, use a suitable resistor (or 2N3055 rigged to

Okay... In addition to having some triacs on hand, the thought also occurs to me to use a complementary cross-coupled pair of transistors in place of that SCR. Collector of each one is tied to the

Perhaps someone here can help - looking for some advice on programming a DQ48F010 and PQ28C65 (flash/EEPROM roms) via a Willem 5.0 programmer - they are not listed (as far as I can see) in the

I am using an SI5351 to generate 10Mhz and 100Mhz digital reference signals via 50ohm 5m long BNC cables but the SI5351 seems to struggle producing a reasonable square waveform at 10Mhz. What would

The overvoltage circuit at https://axotron.se/index_en.php?page=26 ( https://axotron.se/index_en.php?page=26 ) are all effective but the one with the PNP transistor and SCR are the most stable as far

Interesting stuff there. I like the one using a triac, since I have a fair amount of those on hand here. The mention of using small inductance got me to thinking about the ferrite beads and cores I

I've added another file to "Diode Commutation EMI" folder. "Shortwave Hum" is a real world explanation of how bypassing diodes can reduce SW Hum and intermodulation, I copied the web page at

I've added a folder " Diode Commutation EMI" that explain the causes of diode commutation EMI and steps to mitigate it. There are other solutions today, special diodes with controlled turn off

Hello , I am assembling the bits and peaces of what I learned and trying to implement them into my mixer shown in the link below. there is the -174+10log10(BW) of the component my mixer is 10GHZ so

Microsemi became Microchips and changed the numbers on all their technical documents, I'm too busy tonight to find the correct paper. Basically when a diode is reverse biased and goes from conducting

The only thing that made sense about Astron supplies is they sure made/make money. For overvoltage protection?I'd use something like the one shown in https://axotron.se/index_en.php?page=26 I'd

I've seen some stuff out there that puts a cap across rectifier diodes, sometimes just two out of the four, not sure why they'd do that. I also used to see a cap across the AC line, or a
