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...

suggestion of website and book - RF Cafe Forums
RF Cafe Forums closed its virtual doors in 2012 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. If the folks at
phpBB would release a version with integrated
sign-in from the major social media platforms, I would resurrect the RF Cafe Forums,
but until then it is probably not worth the effort. 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.

required me to design a RF bandpass filters for the receiver operating
from 2110-2170MHz, i hope you all can suggest to me which websites and
books suitable for me to learn how to design the required BPF. Hope
for the reply soon, thank you. :lol:

Why would you build one when muRata and Epcos make every kind
of SAW BPF under the sun for the UMTS bands?

What kind of filter do you want to
design, LC, microstrip? Here are couple of good books.
A page for LC design
design programs are here. You find something that helps.

bandpass filter is used in 3G mobile transceiver, is it i am required
to design a LC bandpass filter rather than microstrip type?
book "Radio-Frequency Electronics'' by Jon B. Hagen suitable for me
to learn how to design the bandpass filter? or the two books mentioned
above are more suitable?
"shnt-bpf.mcd", what software is suitable
to open the .mcd file?
Thanx for your reply, Tom. Thank you.
