Software for Designing RF Detector

Hello Sir,

we are currently working on a cell phone detection project which detects GSM 900 and 1800 MHz. we want to first design our circuit on some software, but we are at a fix about the selection of software.

we tried on proteus, but could not find any way to generate 900/1800 MHz radio frequency.

Please suggest some software or some way to generate this frequency in software, which is then detected by the circuit.

thanking in anticipation

Regards.

I assume you are talking about _simulating_ an RF signal at 900/1800 MHz (to be "received" by a simulated cell phone detection circuit). If so, why not just use a simulated sinwave source set to 900/1800 MHz (and adjust the amplitude in terms of micro volts and the impedance to match that of whatever antenna you will be using)? Apply that to the input. I may be _talking through my hat_, though, since I've never used Proteus. But, thought I'd mention it in case it helps.

If you are using microcontroller prescaler or any other component which divide the frequency of the external clock or reference frequency, you may incorporate a Phase Lock Loop (PLL) and Voltage Controlled Oscillator (VCO) in order to generate the required frequency.Or maybe you can try Marconi test instrument signal generator.

That’s a good idea use a Marconi off air test Only £3000 Or there’s the Slumberger another £3 to 4K don’t forget you also have to have the messaging adaptor that’s another £3000 By the time you’ve finished with this that’s 6K before you’ve even got the project off the ground never mind detecting 1800mhz I’m sure there are far cheaper easier methods myself don’t you

Example this is the easy answer

hi .
for this application u have to do direct component test. and choose all components of correct value.implement it on breadborad pr pcb you will get result . make a good antenna for s/g receptions.

where is the link. i wishing to see that..

Try a tuned circuit to respond to 900mhz to 1200Mhz then utilize a pic micro with adc and serial out into a pc possibly the easiest answer probably the best way to tackle that problem or attach the pic micro to an lcd and do you readouts that way Best cheapest solution within a tight budget

Beats the Six grand touch doesent it ? and teaches you the basics of field strength meters

There you go try this

Theres another one for you All you have to do is adapt to suite Page 11 of the download

Not that difficult is it ?
