Lead Free Status / RoHS Status
Lead free / RoHS Compliant
The MAX2654/MAX2655/MAX2656 high third-order
intercept point (IP3), low-noise amplifiers (LNAs) are
designed for applications in GPS, PCS, WLL, and satel-
lite phone systems. The MAX2654/MAX2655/MAX2656
incorporate on-chip internal output matching to 50 ,
eliminating the need for external matching components.
A shutdown feature in the MAX2654/MAX2655 reduces
operating current to 0.1µA, eliminating the need for an
external supply switch.
The MAX2654 operates in the GPS frequency of
1575MHz with 15.1dB of gain, 1.5dB noise figure, and
only consumes 5.8mA. The MAX2655 is designed with
high-input IP3 to improve operation in cellular applica-
tions where the cellular power amplifier leaks into the
GPS receiver. The MAX2656 is designed for PCS
phone applications with 13.5dB of gain in high-gain
mode and 0.8dB of gain in low-gain mode (selected by
a logic control) and 1.9dB noise figure.
The IP3 of MAX2655/MAX2656 is adjustable by a single
external bias resistor (R
be optimized for a specific application.
The MAX2654/MAX2655/MAX2656 operate from +2.7V
to +5.5V single supply and are available in the minia-
ture 6-pin SC70 package.
