GPS LOW NOISE AMPLIFIER WITH

INTEGRATED INPUT/OUTPUT SAW FILTERS

The RF2818 is a GPS Low Noise Amplifier with integrated SAW filters at

the input and output. Low noise figure, along with high gain, achieved by

the RF2818 makes it very suitable for compact GPS receivers requiring

reduced front-end noise and high sensitivity. This module builds upon

RFMD’s leading edge pHEMT process and integrates input matching and

low loss high rejection SAW filters at both the input and output. This

results in high performance and a reduced solution size. The ease of

implementation simplifies the receiver design.

The RF2818 is packaged in a compact 3.0mmx2.5mmx1.0mm package

with only two external components required to achieve the best-in-class

performance.
