Morning guys!(Dont know if we have ladies here?)
I have searched,but get conflicting answers....
My Cband LNB is on the way out,it acts up every now and then.
Iam looking at a new Cband Lnb,just a single output one.
Which one the two is more important when looking for a new one ?(Or is it a combination?Or something completely different?)
1)The conversion Db of it?
2)The noise temp ?
I currently have : MTI AC13-2CV with the specs :
Frequency Range H: 950 - 1450MHz
V: 1500 - 2000MHz
Connector Type 75Ω Female Connector
VSWR 2.5:1 (max)
Local Oscillator
Frequency H: 5.150GHz
V: 5.7GHz
Frequency Stability ±1MHz (max) @ room temp.
±2.5MHz (max) @ -40°C ~ +60°C
Frequency Phase Noise -75dBc/Hz (typ) @ 1kHz @ room temp
-93dBc/Hz (typ) @ 10kHz @ room temp
-105dBc/Hz (typ) @ 100kHz @ room temp
Conversion Performance at Room Temp
Conversion Gain 60dB (min)
Gain Flatness ±5dB (max) over operating band
±1.5dB (max) / 36MHz
Noise Temperature 25°K(max)
Image Rejection 40dB (min)
Cross Polarisation 20dB (typ)
Thanks for the help!
