This chip is fully passivated for enhanced performance and reliability and packaged in RoHScompliant with SOIC-8 surface mount package. It can be used without back side ground soldering. (This may degrade the performance at the high frequency edge.) *All specifications apply to the following test conditions, 1. Device performance _ measured on BeRex E/B at 25°C, 50ohm system. 2. Insertion Loss: Above 3.0dB. 3. Back side ground _ soldered. Applications  Base station Infrastructure  Commercial/Industrial/Military wireless system Absolute Maximum Ratings Parameter Input Power Storage Temperature Operating Temperature Rating 1W CW dBm -55 to +155°C -40 to +85°C Operation of this device above any of these parameters may result in permanent damage. Evaluation Board Drawing Function Block Diagram Pins 1,3,4,6 and 7 must be DC and RF grounded.
