- Low Noise Figure High Small Signal Gain Single +2.7V Operation Power-up Control 50Ω Output Unconditionally Stable Ultra Compact PLLP6 Package Pb-free, RoHS Compliant, Green Benefits Low Power Consumption < 10 mW Very Small, PLLP6 Package (1.6 mm × 2.0 mm) Few External Components 1. Description The ATR0610 is a GPS low-noise amplifie r IC designed for GPS applications. The part uses Atmel’s SiGe1 SiGe technology and is optimized for high linearity, low-noise figure, low BOM and low power consumption. The part features an integrated 50Ω out- put match and is prematched at the input. Due to internal supply blocking, the BOM is minimized. Together with the small footprint of 1.6 mm × 2.0 mm, the LNA allows for a very compact GPS receiver design. Figure 1-1.
