MAX2650

MAX2650 19-1135; Rev 1; 8/03 EVAALVUAAILTAIOBNLEKIT DC-to-Microwave, +5V Low-Noise Amplifier _______________General Description The MAX2650 is a low-noise amplifier for use from DC to microwave frequencies. Operating from a single +5V supply, it has a flat gain response to 900MHz. The MAX2650’s low noise figure and high drive capability make it ideal for a variety of transmit, receive, and buffer applications. The device is internally biased, eliminating the need for external bias resistors or inductors. In a typical application, the only external components needed are input and output blocking capacitors and a VCC bypass capacitor. The MAX2650 comes in a 4-pin SOT143 package, requiring minimal board space. ________________________Applications Wireless Local Loop Global Positioning Systems (GPS) ISM Radios Special Mobile Radios Wireless Local-Area Networks Cellular Base Stations Set-Top Boxes ____________________________Features o Internally Biased o High Gain: 18.3dB at 900MHz o 3.9dB Noise Figure o Single +4.5V to +5.5V Operation o -1dBm Output 1dB Compression Power o Low-Cost Silicon Bipolar Design o Ultra-Small SOT143 Package ______________Ordering Information PART MAX2650EUS-T TEMP RANGE -40°C to +85°C PIN-PACKAGE 4 SOT143-4 __________Typical Operating Circuit __________________Pin Configuration TOP VIEW OUT OUT CBLOCK VCC VCC CBYP GND IN IN MAX2650 CBLOCK OUT 3 4 VCC MAX2650 GND 2 1 IN SOT143 _______________________________________________________...
