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.
