Objective specification

MMIC mixer

BGA2022

FEATURES

• Large frequency range:

– Cellular band (900 MHz)

– PCS band (1900 MHz)

– WLAN band (2.4 GHz).

• High isolation

• High linearity

• High conversion gain.

APPLICATIONS

Receiver side of wireless systems that require high

conversion gain and high linearity at low supply current,

such as CDMA. Trade-off between gain and

intermodulation is determined by one external inductor.

DESCRIPTION

Silicon double poly MMIC mixer in a 6-lead plastic SOT363

package.
