ADL5920 Data Sheet ABSOLUTE MAXIMUM RATINGS THERMAL RESISTANCE Table 2. Parameter Rating
Thermal performance is directly linked to printed circuit board Supply Voltage (VPOS1, VPOS2, and VPOS3) 5.5 V (PCB) design and operating environment. Careful attention to Negative Supply Voltage (VNEG1 and VNEG2) −3 V PCB thermal design is required. Input Average Radio Frequency (RF) Power1 θJA is junction to ambient thermal impedance, and θJC is 50 Ω Load 33 dBm junction to case (exposed pad) thermal impedance. Open or Shorted Load 30 dBm Equivalent Voltage, Sine Wave Input 28.25 V p-p

ESD CAUTION
Lead Temperature (Soldering, 60 sec) 300°C 1 Guaranteed by design based on extended duration bench testing at 85°C case temperature Stresses at or above those listed under Absolute Maximum Ratings may cause permanent damage to the product. This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability. Rev.
