1. “0” = V
2. Only for special operation, e.g. only PA operation, no LNA/switch driver operation
3. Only for special operation, e.g. no switch driver operation
4. Only for special operation
5. Only for special operation, e.g. separate TX/RX antennas, TX and RX operation at the same time
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 19 on page 11. Please note, that for RX_ON below

and duration: load VSWR = 10:1 (all phases) 10 s, Z
1.4 V the T/R switch driver switches to TX mode.
