Low-noise amp saves power, space and
components
The MAX2649 is the industry's first 5GHz low-noise amplifier to integrate a low-power shutdown function.
The MAX2649 is the industry's first 5GHz low-noise amplifier (LNA) to integrate a low-power shutdown function When activated, the LNA draws less than 1uA, preserving battery life in portable 802.11a WLAN and 5GHz cordless phones

Speedy DAC claims dynamic superiority for comms
The MAX5195 is a 14bit 260Msample/s DAC claimed to provide the world's best dynamic performance in spurious-free dynamic range, intermodulation distortion and signal to noise ratio.
The integrated shutdown saves board space and about $0.10 worth of external components.
The MAX2649 provides 17dB gain, 2.1dB noise figure, and 0dBm input IP3 at 5.2GHz while consuming only 12.5mA.
The high-gain, low-noise, and high-linearity performance make it flexible for use as a first- or second-stage LNA, an LO buffer, or a transmitter driver amplifier.
The MAX2649 is designed on a proprietary low-noise, advanced silicon germanium (SiGe) process optimised for high-frequency applications.
Its performance compares favourably to that offered by more expensive GaAs ICs, which are typically 12 to 15dB gain and 2.5dB noise figure.
Compared with discrete designs, the MAX2649's integrated active bias network saves one transistor and three passive components, while maintaining stable RF performance over supply and temperature variations.
The LNA is available in the compact 2 x 3 UCSP chip-scale package measuring 1.0 x 1.5mm, 60% smaller than an SC70.
Total board space required is only 11mm2.
Prices start at $1.25 (1000-up, FOB USA).
A fully assembled evaluation kit (MAX2649EVKIT) is available to help reduce design time.
