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

and duration: VSWR = 8:1 (all phases) 10 s, ZG = 50 Ω, VS = 3.6 V.

2. With external matching network, load impedance 50 Ω.

3. Low-noise amplifier shall be unconditionally stable.

4. With external matching components.
