PicoGuard XS devices integrate low capacitance diodes with inductors to enable high frequency ESD protection and provide matching impedance without requiring external compensation, and are ideal solutions for ports such as HDMI(R) 1.
For cellular infrastructure and WiMAX base station OEMs dependant on maximizing power and efficiency, RFMD's GaN transistors provide higher at-package matching impedance, higher power density and wider bandwidth performance when compared with silicon LDMOS devices," said Bill Pratt, Co-founder, Chief Technical Officer and Corporate Vice President for RFMD.
The important issue is that any value that is close to matching impedances will result in reduced reflections.
