Notes:

1. Operation in excess of any one of these conditions may result in

permanent damage to the device.

2. Ground lead temperature is 25°C. Derate 20 mW/°C for Tc > 131.5

°C.

3. Thermal Resistance is measured from junction to board using IR

method.

1. Typical value determined from a sample size of 500 parts from 3 wafers.

2. Measurement obtained using production test board described in the block diagram below.

3. i) 100 MHz OIP3 Test Condition: F1 = 100 MHz, F2 = 105 MHz, Pin = -20 dBm per tone.

ii)900 MHz OIP3 Test Condition: F1 = 900 MHz, F2 = 905 MHz, Pin = -20 dBm per tone.

iii) 2000 MHz OIP3 Test Condition: F1 = 2000 MHz, F2 = 2005 MHz, Pin = -20 dBm per tone.
