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.
