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.

The MAX2406 low-noise amplifier (LNA)/downconverter mixer is designed for use over a wide range of frequencies and is optimized for communications systems operating at a frequency of 1.9GHz. Applications include PWT1900/DCT1900, DCS1800/PCS1900, PHS, and DECT. This device includes an LNA, a downconverter mixer, and a local-oscillator (LO) buffer in a lowcost, plastic surface-mount package. At 1.9GHz, the LNA has 2.5dB typical noise figure and a -9.5dBm input third-order intercept point (IP3). The downconverter mixer has a low 9.1dB noise figure and a 4.5dBm input IP3. Image and LO filtering are implemented off-chip for maximum flexibility.

The MAX2406 has a differential IF port that can be used in a single-ended configuration by tying the unused side to V_CC. The LO buffer can be driven differentially or in a single-ended configuration with only -10dBm of LO power. Power consumption is 60mW in receive mode, and typically drops to less than 1µW in shutdown mode.

For transceiver applications, the MAX2410 or MAX2411A both offer a transmitter along with a similar receiver.
