If you add a DC blocking cap in series with one of the mixer diodes, the mixer will not work anymore as a single-balanced diode mixer. Would be a single-diode mixer, which is the simplest form of an RF mixer. For reasonable up-conversion performances you have to use a double-balanced mixer, which provides better ports isolation than other mixer typ
Assuming a constant slope in double logarithmic R versus illumination plot is just a simplification. In contrast to the 0.75 slope given by vGoodtimes, I see "gamma" numbers of 0.8 to 0.95 for PE/Excelitas photocells. Real LDR photocells have more or less bent curves in the double logarith
Most inverters are able to deal with a reasonable range of regulation, once they perform a double conversion ( AC/DC - DC/AC ) therefore it is already expected an output compensation due to the battery discharge, so you shoulg check if its regulation satisfy your need.
Hi, what topology are u using, single conversion, double conversion, what voltage are you inverting from. you have to say. Many times what you give is what you have. even if u parallel a 100 Mosfets if there is no where to source it you cant sink it. Thats one of the rule of thumb in Electronics. Enumerate further share your idea very well (...)
What @chuckey has suggested you it's called "online/double conversion ups". It means that you permanently feed your load from the inverter and only switch the battery with a mains powered power supply. Anyway, the true online/double conversion ups never disconnect the battery and you could do the same. I guess you (...)
Hello, I am designing 'double down conversion of superhyterodyne receiver' for the frequency range of 54MHz - 860 MHz . I am using the following design. Here I have given 700 MHz as RF input. 102933 Design parameters set are unable to generate the frequency response & respective voltage output, noise figure, S param
Can anyone guide me about designing superheterodyne receiver in advanced design system (ADS)? Anybody has a concrete reference of the designed receiver in ADS? I want to design a double down conversion superheterodyne receiver. Which analysis should be used envelope, Harmonic Balance, transient etc.? Thanks.
Hi; I ve to convert this double integral from Cartesian to polar coordinates \iintf(x,y)dxdy -a
Hi; You can use "reshape" function to make 1x65536 vector to a 256x256 matrix. And here display a double matix as an image (uint). hope helps
how a resistive feedback inverter act as a buffer ? thank u in advance if anyone knows the answer please post soon
Tuning the LO calls for a tunable filter which is difficult. The best way then is to use the double conversion, with the second IF around 400--500 MHz. An easier way is to choose two or three (etc.) LO frequencies for which you can design good filters, to reject the LO leak and image, too. Another option is to upconvert first to say 5-6 GHz band,

here i am using mplab c18 compiler to try to display '1234567890' value as it on lcd unsigned char sachin; unsigned double voltage = 0,step = 3215820; voltage = 1234567890; sachin = (char)(voltage/1000000000) + 0x30; sachin = '.'; sachin = (char)(voltage/100000000)%10 + 0x30; sachin = (char)(voltage/10000000)%10 + 0x30; sachin[4
Image frequency is well filtered by using low frequency sharp filters, that's why double and sometimes triple conversion is applied.For instance ceramic filters, SAW filters etc.
For a binary to decimal conversion that doesn't involve division/modulo function, you may want to review the double dabble algorithm. In C-programming, itoa() or sprintf() are mostly the reasonable method.
In cadence there are two ideal balun, one from rflib and other from analoglib. so which one suppose to use in designing mixer to convert single input rf to double output. thank you
I think its perfectly possible theoretically There are many commercial doublers using this principle. Check those by MiniCircuits. Such doublers need typically +17...+20 dBm to saturate the diode pair or quad, output power can be +4...+8 dBm over wider bnd.
Can someone recommend a handy frequency planning tool for things such as double-conversion or multiple-conversion radio? Thanks a lot.
could somebody pls tell me how to convert double precision into network byte ordering. i tried uint32_t htonl(uint32_t hostlong); uint16_t htons(uint16_t hostshort); uint32_t ntohl(uint32_t netlong); uint16_t ntohs(uint16_t netshort); functions and they worked well but no of them does double (float) conversion cuz these types are (...)
Hi All, I have designed a double conversion upconverter. Both PLL's use a 10 Mhz TXCO as reference. I should also be able to use an external 10 Mhz reference. Any suggestions on how to use only one 10 Mhz TXCO for both PLL's and to how to switch to an external reference?
