T_jc = 49.4°C/W per channel
Notes:
2. Operation of this device in excess of any of
these limits may cause permanent damage.
3. Thermal resistance measured using Infra-Red
Measurement Technique with both channels
turned on hence I_{dd_total}=100mA.
4. Power dissipation with both channels turned
on. Board temperature T_B is 25°C. Derate at
20mW/°C for T_B>100°C.
Electrical Specifications ^[7-10]

Notes:
7. Measurements at 850 MHz and 900 MHz are obtained using demo board described in Figure 5.
8. IIP3 test condition:
a. F_RF1 = 850 MHz, F_RF2 = 851 MHz with input power of -15dBm per tone.
b. F_RF1 = 900 MHz, F_RF2 = 901MHz with input power of -15dBm per tone.
9. For NF data, board losses of the input have not been de-embedded.
10. Use proper bias, heatsink and derating to ensure maximum channel temperature is not exceeded. See absolute maximum ratings and application
note for more details.
