1700-2200 MHz High Gain & Linearity Diversity Downconversion Mixer

The SKY73021 is a fully integrated diversity mixer that includes LO drivers, an LO switch, high linearity mixers, and large dynamic range IF amplifiers. Low loss RF baluns have also been included to reduce design complications and lower system cost.

The SKY73021 is an ideal solution for high dynamic range systems such as 2G/3G base station receivers. The LO switch provides more than 50 dB of isolation between LO inputs and supports the switching time required for GSM/EDGE base stations.

Please note: SKY73021-11 is not recommended for new designs. Recommended replacement parts is SKY73421-11.
