Insertion Loss Calculation
Insertion Loss (dB/in @ Freq (GHz)) = L x [( k1 x F ) + ( k2 x F ) ] / 1200 + Connector Loss
Where:
IL = Insertion Loss (dB)
L = Length (in)
F = Frequency (GHz)
VSWR Guide
VSWR values are provided for various interfaces and frequencies. Contact the factory for detailed VSWR specifications.
Power Handling
Average power ratings are provided for various connector interfaces and cable types, based on VSWR of 1.0:1, at sea level and an ambient temperature of 25 C. Derating factors for temperature and altitude are available.
| Connector | Avg Power* (kW) | Peak Power (kW) |
|---|---|---|
| SMA | 0.1 | 2.5 |
| N | 0.6 | 10 |
| TNC | 0.3 | 5.6 |
*Average power ratings of connector interfaces are typical for most applications and based on 900MHz.
