Dear Brian, the resistor is not for signal and power source separation (you need an inductor to have an high impedance at high frequency). I found the reason is that the resistor is part of the biasing network, essentially for thermal feedback. In any case, thanks for your answer.
I cannot figure out why in the datasheet of minicircuit amplifier (like ERA3, ERA5, etc) there is a "required" resistor.
Suppose I have a power supply of 12 V, and a switching for other function to obtain 5 V.
If a monolithic works at 5V, I think the best choice is to apply a voltage coming for...
Dear all,
I'd like to know where to obtain a reference for a VSB modulator scheme, or simply what type of filter is generally used in Trasmission.
I'm unable to find the VSB specification for a PAL transmission.
Thank you all
Dear all,
can you helo me to find a sort of tutorial or information in how to design a cooling system for my devices.
More precisely, sometimes the temperature of my "processors" exceed a certain value and I should activate a brushless fun. However, I don't know how to select the brushless...
Re: How can I realize an UP converter from 300 MHZ to UHF ba
Thank Biff, that was my idea (I've bad exaplined).
There are a lot of surface mount mixers out there, can you suggest me some of them?
Is there exists an integrated mixer and VCO, or mixer and PLL ?
I can obtain by a DAC a DVB-T signal up to 350 MHz.
Which is the best up-conversion scheme to the entire UHF band (474 - 860 MHz) in order to use as few as possible Output filter (to overcome spurs & clock).
Can you suggest me some circuit elements such as VCO/PLL and mixer ?
Thank you all...
