RF Connector Power Handling

Theoretical Performance and Power Limits

This chart represents a matched impedance connection (50 ohms) with a VSWR < 1.35:1.

Power handling is not absolute and can be reduced by up to 50% based on:

• Environmental Factors
• VSWR Fluctuations
• Connector Manufacturer Standards
• Internal Voltage Breakdown

Actual maximum power levels at lower frequencies are determined by the following constant:

$P = \frac{k}{\sqrt{F}}$

Where:
P: Power in Watts | F: Frequency in MHz | k: Constant value

CASE STUDY

Example: An N-type connector can handle 1000W @ 1GHz under optimized conditions. This assumes maximum accepted power at a given frequency.
