5GHz SiGe LNA PROVIDES 1.8dB NF FOR 802.11a AND HiperLAN2 WLAN SYSTEMS
SUNNYVALE, CA-February 5, 2001-Maxim Integrated Products announces the industry's first 5GHz SiGe LNA optimized for 802.11a and HiperLAN2 WLAN systems. The MAX2648 provides 17dB gain, 1.8dB noise figure, and 0dBm input IP3 at 5.2GHz while consuming only 12mA. The high gain, low noise, and high linearity performance make it flexible for use as a first stage LNA, an LO buffer, or a transmitter driver amplifier.
The MAX2648 is designed on a proprietary low noise, advanced silicon germanium (SiGe) process optimized for high-frequency applications. The LNA's 17dB gain and 1.8dB noise figure compare favorably to the performance offered by more expensive GaAs ICs, which typically have 12dB to 15dB of gain and a 2.5dB noise figure. Compared to discrete designs, the MAX2648'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 packaged in the ultra-small 2 x 3 CSP (chip scale package), measuring 1.0mm x 1.5mm, which is 60% smaller than the SC70 package. Total board space required is only 11mm2. Pricing starts at $1.25 (1000-up, FOB USA). A fully assembled evaluation kit (MAX2648EVKIT) is available to help reduce design time.
