Thermal Resistance ^[2] θ_jc = 106.3°C/W
(Vc = 1V, Vsupply = 2.7V, Tc = 85°C)
Notes:
1. Operation in excess of any one of these
limits may result in permanent damage to the
device.
2. Thermal resistance is measured from junction
to case using Infra-Red method.

Notes:
4. Data above is obtained using demo board shown in Figure 32 and 33.
5. 2-tone IIP3 test condition: F_RF1, F_RF2 = 1.1MHz separation, Input power = 22dBm
6. IP1dB measured with 12.5% duty cycle.
7. The performance above obtained with phase compensation inductor value based on the table 1 below.
8. Use proper biasing, heat sink and de-rating to ensure maximum channel temperature is not exceeded. See absolute maximum ratings and
application note (if applicable) for more details.
