(Vd = 5.0 V, Id = 320 mA, Tc = 85°C)
Tjc = 20°C/W
Notes:
1. Operation of this device in excess of any of
these limits may cause permanent damage.
2. Ground Paddle temperature is 25° C. Derate
50 mW/°C for Tc > 95° C.
3. Thermal resistance measured using 150° C
Infra-Red Microscopy Technique.
4. Vc1/Vc2 ≤ Vdd1/Vdd2.

Notes:
1. Measured with output match tuned to frequency as specified. See Table 3 for component values.
2. OIP3 test condition: FRF1 - FRF2 = 1 MHz with input power of -8 dBm per tone measured at worst side band.
3. Peak-to-average power ratio = 7.5 dB. Measured on Agilent MXA N9020A with low-noise option. Refer to Figure 77 for CCDF.
