As David said, yes it's the power, no it's not the rms power. Vrms is the (square)Root of the Mean of the Squares (of the Voltage samples). When you work out Vrms^2 in order to work out the power, yo
The class labels are used just the same, and are applied in similar situations. AB1 is usually used to describe class AB with low quiescent bias, AB2 with higher quiescent bias - you don't have the e
That's the way I view it. You draw a load line on the constant current curves, and the class of operation is defined by where you put the bias point - irrespective of the device that's being used. Ch
It's probably not long until 36V car electrics become commonplace. Steve _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/list
60+% is easy with semiconductors, provided you're not trying to do it over 4 octaves 'no tune'. Same as a tube, really :-) Steve _______________________________________________ Amps mailing list Amps
If I understand it correctly, the current that's shunted to ground at the input contains lots of harmonics. A capacitor at the cathode acts as a shunt to these. A remote matching network at the other
I think that Curie temp. is the point at which the magnetic properties change (it's how old type Weller irons do temperature control) but it's not necessarily destructive. Some materials recover afte
Philips and Thomson keep on going after Mot (or should we say M/ACom?) run out of puff. You might also like to look at Semelab D1028/1029 which are doing lots of business in DAB transmitters. Wish I
If it wasn't for bills to pay, I'd offer to do it for free, just for the fun. Maybe if I slim down a bit I might squeeze inside your budget :-) Steve _______________________________________________ A
Depending on your definition of reasonable, try your local branch of Richardson Electronics - www.rell.com or - BFI Ibexa for Anaren or RF Power products. These are V/UHF resistors with stripline tab
For comparison, RF Power 250W 50ohm RFP250-50TC termination from Richardson is $9.92 list (basically the same as RFP250-50TG but different flange size). RFP250-50RM 250W 50ohm resistor (both ends flo

I got the price from the web site - don't know how far you got into it, but it's **AWFUL** to use. The search function won't find these parts, even if you put in the exact part number. The route is w

A had a few minutes before leaving the office yesterday, so I fired up the network analyser. I made some rough, not precision, measurements and, as these were done on a cold tube lying on the bench I

A suggestion for anyone planning to copy this - get 8 fets from one batch, so the gate thresholds are likely to be close together. IR specify a range of 2-4V so a mix could end up with only some bein
Tests on a NOS 811 (dated 1944): The filament - grid circuit shows goes through 'short' at about 200MHz, and 'open' at about 500MHz. Feed through (50 ohm source and load) is -40dB or lower up to 100M
I should have said there's the alternative to measure them instead. Perhaps they were all from the same wafer run, but packaged at different times, or maybe the process control is easier than with rf
