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, Z G = 50Ω. 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 9-16 on page 11. Please note, that for RX_ON below 1.4V the T/R switch driver switches to TX mode. |
