________________General Description

The MAX2406 low-noise amplifier (LNA)/downconverter

mixer is designed for use over a wide range of frequen-

cies 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 downcon-

verter mixer, and a local-oscillator (LO) buffer in a low-

cost, 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

. 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 shut-

down mode.

For transceiver applications, the MAX2410 or

MAX2411A both offer a transmitter along with a similar

receiver.
