LNAs with multiple gain states suit HSPA/LTE apps
Suited for high-data-rate wireless protocols such as HSPA/LTE applications, the MAX2666/2668 LNAs feature three programmable gain states, allowing customers to dynamically adjust linearity and sensitivity to optimize system performance in the face of varying input-signal strengths. If interference from adjacent signals is particularly high, the gain can be increased to maintain optimum blocker performance.
The parts deliver 15 dB of gain, feature a low 1.0-dB noise figure for improved receive sensitivity over discrete or CMOS solutions, and operate over the I, IV, V, VI, VII, and X UMTS frequency bands. The LNAs operate with a low 3.8-mA typ supply current and less than 100 μA in the lowest gain mode. They run off of a 2.7 to 3.3-V supply. Fully specified over the –40° to 85°C extended temperature range, the parts are available in a 6-pin ultrathin LGA package. (From $0.65 ea/1,000 — available now.)
