Contact Zarlink Semiconductor sales outlet for a separate datasheet.) ±6.0V -65°C to +175°C +175°C 15.5°C/W 76.5°C/W ±400mV +15dBm ESD PROTECTION To achieve the high frequency performance there are no ESD protection structures on the RF input pins (27, 28). These pins are highly static sensitive, typically measured as 250V using MIL-STD-883 method 3015. Therefore, ESD handling precautions are essential to avoid degradation of performance or permanent damage to this device.
