Notes:

1. Power amplifier shall be unconditionally stable, maximum duty cycle 100%, true CW operation, maximum load mismatch

2. With external matching network, load impedance 50

Ω.

3. Low-noise amplifier shall be unconditionally stable.

4. With external matching components.

5. LNA gain can be adjusted with RX_ON voltage according to Figure 9-10 on page 9. Please note, that for RX_ON below

1.4V the T/R switch driver switches to TX mode.
