Typical Applications
• Tri-Band EGSM/DCS/PCS Handsets
RF2417
TRI-BAND LOW NOISE AMPLIFIER
• Dual-Band EGSM/DCS Handsets
Product Description
The RF2417 is a highly-integrated, low-power and low-
cost tri-band LNA for EGSM-based multi-band handset
applications. All input and output ports include on-chip
matching, thus minimizing external components. The
device supports the worldwide EGSM and DCS bands
and the North American PCS band. A 20dB gain reduc-
tion mode is provided. Three mode-control pins control
gain and band selection. Unused functions are powered
down for the lowest power consumption. The RF2417 is
packaged in a 3mmx3mm, 16-pin leadless chip carrier,
and is manufactured in the Silicon Germanium (SiGe
HBT) process technology.
