Sensitivity, 1dB Compression Point and Dynamic Range

Sensitivity

• The smallest RF Signal that can produce a useful baseband signal at the receiver output.
• Determine how far the receiver can be from the transmitter and still receive an understandable message.

1dB Compression Point

• The point at which the output power differs from the ideal transfer function by 1dB as the input power increases.

Dynamic Range

• The input power range over which the receiver provides a useful output. The low power limit is the sensitivity specification and upper limit is the input power at 1dB compression point.

Dynamic Range = Input 1dB Compression Point - Sensitivity Level
