MAX2654, MAX2655, MAX2656 pdf

The MAX2654/MAX2655/MAX2656 high third-orderintercept point (IP3), low-noise amplifiers (LNAs) aredesigned for applicaTIons in GPS, PCS, WLL, and satellitephone systems. The MAX2654/MAX2655/MAX2656incorporate on-chip internal output matching to 50Ω,eliminaTIng the need for external matching components.A shutdown feature in the MAX2654/MAX2655 reducesoperaTIng current to 0.1μA, eliminaTIng the need for anexternal supply switch.The MAX2654 operates in the GPS frequency of1575MHz with 15.1dB of gain, 1.5dB noise figure, andonly consumes 5.8mA. The MAX2655 is designed withhigh-input IP3 to improve operation in cellular applicationswhere the cellular power amplifier leaks into theGPS receiver. The MAX2656 is designed for PCSphone applications with 13.5dB of gain in high-gainmode and 0.8dB of gain in low-gain mode (selected bya logic control) and 1.9dB noise figure.The IP3 of MAX2655/MAX2656 is adjustable by a singleexternal bias resistor (RBIAS), allowing supply current tobe optimized for a specific application.The MAX2654/MAX2655/MAX2656 operate from +2.7Vto +5.5V single supply and are available in the miniature6-pin SC70 package.________________________ApplicationsGPS ReceiversGPS Receivers in Cell PhonesDCS/PCS Cell PhonesSatellite PhonesWireless Local Loop
