Notes: 1. Power amplifier shall be unconditionally stable, maximum duty cycle 100%, true CW operation, maximum load mismatch
and duration: load VSWR = 10:1 (all phases) 10s, ZG = 50Ω.
2. With external matching network, load impedance 50Ω.
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 9-16 on page 11. Please note, that for RX_ON below
1.4V the T/R switch driver switches to TX mode.
