MAX2410 Datasheet | Maxim Integrated

Description The MAX2410 performs the RF front-end transmit/receive function in time-division-duplex (TDD) munication systems. It operates over a wide frequency range and is optimized for RF frequencies around 1.9GHz. Applications include most popular cordless and PCS standards. The MAX2410 contains a low-noise amplifier (LNA), a downconverter mixer, a local-oscillator (LO) buffer, an upconverter mixer, and a variable-gain power-amplifier (PA) driver in a low-cost, plastic surface-mount package. The LNA has a 2.4d B (typical) noise figure and a -10d Bm input third-order intercept point (IP3). The downconverter mixer has a low 9.8d B noise figure and a 3.3d Bm IP3. Image and LO filtering are implemented offchip for maximum flexibility. The PA driver has 15d B of gain, which can be reduced over a 35d B (typical) range. Power consumption is only 60m W in receive mode or 90m W in transmit mode and drops to less than 0.3µW in shutdown mode. A similar part, the MAX2411A, features the same functionality as the MAX2410 but offers a differential bidirectional (transmit and receive) IF port. This allows the use of a single IF filter for transmit (TX) and receive (RX). For applications requiring a receive function only, consult the data sheet for the MAX2406, a low-cost downconverter with low-noise amplifier. _______________Ordering Information PART MAX2410EEI MAX2410E/D TEMP.
