Hundreds of other connector designs are available for special requirements including high power, swept bends, environmental sealing, low intermod characteristics, and special plating.
Cable Insertion Loss Calculation
Formula: IL = L x [( k1 x F ) + ( k2 x F ) ] / 1200 + Connector Loss
Where:
- IL = Insertion Loss (dB)
- L = Length (in)
- F = Frequency (GHz)
