Notes:

1) Normal mode: connect VSS_EXT (pin 12) to GND (VSS_EXT = 0V) to enable internal negative voltage generator.

2) Bypass mode: use VSS_EXT (pin 12) to bypass and disable internal negative voltage generator.

3) The input 0.1dB compression point is a linearity figure of merit. Refer to Table 2 for the operating RF input power (75

Ω).
