General Description

The MAX2648 high-linearity, silicon-germanium (SiGe)

low-noise amplifier (LNA) is designed for 5GHz wireless

LAN systems based on IEEE 802.11a and HiperLAN2

standards. The LNA provides high gain, low noise, and

high linearity performance, allowing it to be used as a

first-stage LNA, an LO buffer, or a transmitter driver

amplifier. This highly versatile amplifier provides 17dB

gain, 1.8dB noise figure, and 0dBm input third-order

intercept point (IIP3) while consuming only 12mA.

The MAX2648 is designed on a low-noise, advanced

SiGe process optimized for high-frequency applica-

tions. It operates over a +2.7V to +3.6V supply range.

The device is packaged in a tiny 2

3 chipscale pack-

age (UCSP™) with six solder bumps, measuring 1.0mm

1.5mm.
