Note: exceeding any of the max. ratings may cause permanent damage to the device. Appropriate handling is
required to protect the electrostatic sensitive MMIC against degradation due to excess current spikes. Proper
ground connection of leads 1 and 3 ( with minimum inductance ) is required to achieve the guaranteed RF
performance, stable operating conditions and adequate tuning.
1) Dimensions see chapter Package Outlines
2) See application circuit.
3) TS is measured on the source 1 lead at the soldering point to the PCB.
