900MHZ 3V LOW CURRENT LNA/MIXER

Typical Applications

• UHF Digital and Analog Receivers

• Commercial and Consumer Systems

• Digital Communication Systems

• Portable Battery-Powered Equipment

• Spread-Spectrum Communication Systems • General Purpose Frequency Conversion

Product Description

The RF2495 is a front-end receiver IC chip developed for

the handset/portable battery-powered equipment mar-

kets. The chip contains an RF 15dB attenuator, an LNA

and a passive mixer. By using a state-of-the-art Silicon

Bi-CMOS process, the LNA has high dynamic range

under low DC operating conditions and the passive mixer

requires no DC bias at all. Packaged in the industry-stan-

dard MSOP-10 package, the device is well-suited for lim-

ited board space applications.
