Description
The PTFA080551E and PTFA080551F are 55-watt, internally
matched GOLDMOS
®
FETs intended for EDGE and CDMA
applications in the 869 to 960 MHz band. Thermally-enhanced
packaging provides the coolest operation available. Full gold
metallization ensures excellent device lifetime and reliability.
