Operating Frequency 950 to 2150 MHz L-Band, 100 Hz frequency resolution
Operating Bandwidth All carriers must be within 70 MHz
Connector Type N (female)
Impedance 50 Ω
Return Loss 18 dB, minimum (typical 20 dB)
Input Power Range, Desired Carrier -130 + 10 log(symbol rate) to -80 + 10 log(symbol rate) dBm
