EVALUATION KIT AVAILABLE MAX2687/MAX2689/MAX2694 GPS/GNSS Low-Noise Amplifiers General Description Features The MAX2687/MAX2689/MAX2694 low-noise amplifiers S High Power Gain: 17.8dB (MAX2687) (LNAs) are designed for GPS L1, Galileo, and GLONASS S Low Noise Figure: 0.85dB (MAX2687) applications. Designed in Maxims advanced SiGe pro- S Integrated 50 Output Matching Circuit cess, the devices achieve high gain and low noise figure S Low Supply Current: 4.5mA (MAX2694) while maximizing the input-referred 1dB compression point and the 3rd-order intercept point. The MAX2687/ S Wide Supply Voltage Range: 1.6V to 3.6V MAX2689/MAX2694 provide high gains of 12dB, 15dB, S Low Bill of Materials: One Inductor, Two and 18dB, respectively. Each is optimized for high Capacitors linearity. S Small Footprint: 0.86mm x 0.86mm The devices operate from a +1.6V to +3.6V single sup- S 0.4mm-Pitch Wafer-Level Package (WLP) ply. The optional shutdown feature in the devices reduc- es the supply current to less than 10FA. The devices are available in a very small, lead-free, RoHS-compliant, 0.86mm x 0.86mm x 0.65mm wafer-level package (WLP).

CAUTION ESD SENSITIVE DEVICE Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. PACKAGE THERMAL CHARACTERISTICS (Note 2) WLP Junction-to-Ambient Thermal Resistance (q ) ........103C/W JA Note 2: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.
