MAX2666/MAX2668 19-5479 Rev 0 8/10 Tiny Low-Noise Amplifiers for HSPA/LTE General Description Features The MAX2666/MAX2668 are a family of low-noise ampli- S Small Footprint: 1mm x 1.5mm Package fiers (LNAs) intended for use in HSPA mobile handsets. S Thin Profile: 0.55mm The LNAs provide three programmable gain states, S Low Noise Figure delivering superior optimization for linearity and sensitiv- 1dB for MAX2668 ity versus traditional two-gain-state LNAs. 1.1dB for MAX2666 The MAX2666 is optimized for use over the 2100MHz S Three Gain States for Optimum Blocker Handling to 2200MHz frequency range (bands 1, 4, and 10) and S 3.8mA Low Supply Current offers a typical maximum gain of 14.5dB. S Low Bill of Materials The MAX2668 is optimized for use over the 850MHz to 1000MHz frequency range (bands 5, 6, and 8) and pro- vides a typical maximum gain of 17dB. Each device is available in a tiny 1mm x 1.5mm, 6-pin ultra-thin LGA package.
