Text preview for : RJL01_1.5_1.7GHz_GPS_LNA_.pdf part of Rficsolutions Inc. RJL01 The RJL01 is 1.5 to 1.7 GHz, Low Noise Amplifier
IP Block. The LNA is designed on the 0.18um SiGe
BiCMOS Process. The device is designed for GPS
system. The LNA has provision for mode control to
turn off.
It requires a single +3.0 Volt supply and consumes
only 12 mA current. The simulated noise figure is
0.5 at 1.575 GHz.
