IF output
The signal at this connector is the downconverter's output.
•
Nominal output level: 0 to +5 dBm (input signal ≥ – 30 dBm)
•
Maximum output level: +15 dBm
•
Frequency (RF input 5 to 1500 MHz): 5 to 1500 MHz
•
Frequency (RF input 1.5 to 26.5 GHz): 300 to 900 MHz
The IF amplifiers frequency response starts rolling off above 1200 MHz. It is
best to avoid using IF frequency between 1200 and 1500 MHz.
•
Output impedance: 50
