Measured with a Noise/Com CDMA Generator (12 dB peak- to-average ratio). Third-Order Two-Tone Frequency = 1960 MHz Tempterature = +25 °C Note: 1. CDMA adjacent power and spurious measurements are made using a Rohde & Schwarz SMIQ03 source in an IS-95 forward link mode. 2. This unit is to be mounted on a ground plane and thermal heat sink, with a maximum heat sink temperature of +85°C.
