5GHz ^{EVFAOLLULAOTWIOSNDKAITTAMSAHNEUEATL} to 6GHz Low-Noise Amplifier
in 6-Pin UCSP
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.

o 5GHz to 6GHz Wideband Operation
o Low Noise Figure: 1.8dB at 5.25GHz
o High Gain: 17dB
o High IIP3: 0dBm
o +2.7V to +3.6V Single-Supply Operation
o Chip-Scale Package (UCSP) Measuring
1.0mm ✕ 1.5mm
