May i know the
following specs
1. What is the tx and rx isolation of umtrx?
2. What is the power output in dbm of your umtrx?
After fixing this
issue<https://code.google.com/p/umtrx/issues/detail?id=41&can=1&…
measured + 20 dBm for 900 MHz band and +17 dBm for 1800.
3. How is the lna on the rx input and is an
external lna and bpf
recommended?
For Fairwaves 10W base stations we're developing UmSEL, which has
channel filter and an additional LNA. For the use without amplifier
you don't need any additional filters or LNAs.
4. What is the main advantage of umtrx compared
to usrp by ettus?
If you want to use it for GSM, then it's cheaper and gives you
dual-channel support.
