10 discussions on ElectronDepot about the Analog Devices AD834: what owners asked, what went wrong, and what fixed it.
If I hypothetically had a 10 MHz reference and wanted to lock a 155.52 MHz VCXO to it, the obvious way would be to divide both down to 80 KHz (the GCD) and drive a phase detector back into the VCXO. But that's a pretty low frequency to run...
These look great, very high Q. I'm thinking about a 50 or maybe 100 MHz Colpitts oscillator PLL. I wonder if the thermal expansion tempco of the FR4 board will stretch the coil and change its native tempco. FR4 is variously cited as being...
What are some optocouplers you like that would be good for designs where they're used in unusual ways, like that "HV Opamp" thing JL likes where they're used as the "output stage" of an amplifier? Are any characteristics that I should...
Gentlemen, Say I want to rectify RF of up to 30Mhz so I can read its amplitude with a milivoltmeter, what sort of diode would be suitable? I'm guessing I can't use a common 1Nxxxs series jellybean as I would for 50 or 60Hz; I'd need a fast...
A Spice Model for the ADI 500MHz Four-Quadrant Multiplier has been added (AD834_SPICE_Model.zip) to the Device Models & Subcircuits Page of my Website, with... * Improper modeling syntax corrected by Jim Thompson on 2015_01_16: * * "...
HII need a simple circuit for AM modulation using multiplier IC .Pleasegive links where i can find applications,datasheets and relatedinformations of multipler Ics for AM modulation. I have to demodulatethe same using envelope You!
