I need help in choosing a simulation
package(software) to simulate a GSM phone repeater operating on
1900 MHz or 850 MHz which are the 2 main frequency band used in
Does anybody knows how to do this or anybody have
done this simulation and I need help to first simulate this and
then of course impelment the unit. However, at this stage I only
need the simulation and the results to have an output of around
1W or less. (the maximum allowed based on government regulations
and spectrum canada is 2Watts).
The components and parts
I would like to use are Antenna, Duplxere, LNA (low noise amplifiers),
and of course the band-pass filter and maybe another stage of power
amplifier after the band-pass filter for uplink and the offset frequency
for the downlink with the same components for the downstream. I
can also send you my overall design on paper and the range of frequency
I want to simulate if it will help you more.1850 - 1910 MHz( uplink)
1930 - 1990 MHz (downlink)
Thanks a lot

The choice of a simulator
depends on a number of things:
1. What kind of results do you
need? Power, distortion, impedance, BER?
2. What do you have
to provide the simulator? Detailed schematic with specific parts,
with available models? Or just "10 dB amplifier" for one stage?
3. What kind of budget (time and money do you have? An associated
question: Will you use the simulator again, or must its costs be
allocated totally to this repeater project?
4. What kind of filters
are you considering? Make or buy?
All these affect your choice.
