simulation and results for a GSM cellphone repeater for home - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2010 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

NOTICE: The original RF Cafe Forum is available again for reading, and the new RF Cafe Blog is an active board.

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 Canada.

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

Hi Tony,

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.

Good Luck!

    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
