Maxim introduces LNAs for high data rate wireless protocols

Maxim Integrated Products has released the MAX2666/MAX2668 low-noise amplifiers (LNAs) for high-data-rate wireless protocols such as HSPA and LTE. Each LNA features 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, as is often the case with mobile devices, the gain can be increased to maintain optimum blocker performance. Ensuring peak system performance regardless of signal conditions, the MAX2666/MAX2668 are well suited for HSPA/LTE based radio systems such as smartphones and tablets.

MAX2666/MAX2668 deliver 15dB of gain; feature a low 1.0dB noise figure; and operate over the I, IV, V, VI, VII, and X UMTS frequency bands. Maxim's innovative design enables a tiny package (1.5mm x 1.0mm x 0.55mm) for use in applications such as handheld devices and cellular-based data cards. Requires a single external component is required to complete the board-level design.

The MAX2666/MAX2668 operate with a low 3.8mA (typ) supply current and less than 100microamps in the lowest gain mode. They run off of a 2.7V to 3.3V supply.

Package: 6-pin, ultra-thin land-grid array (LGA) package.

Operating temperature range: -40 degrees Celsius to +85 degrees Celsius

Price: Start at US$0.65
