650-950 MHz Broadband, Application Configurable High Gain and Linearity Diversity Downconversion Mixer

Please note: SKY73420-11 is being discontinued and is not recommended for new designs.

The SKY73420-11 is a fully integrated diversity mixer that includes Local Oscillator (LO) drivers, high linearity mixers, and large dynamic range Intermediate Frequency (IF) amplifiers. Low loss RF baluns have also been included to reduce design complications and lower system cost.

The SKY73420-11 features an IIP3 of up to +25.6 dBm and a Noise Figure (NF) of 9.3 dB, making the device an ideal solution for high dynamic range systems such as 2G/3G/4G base station receivers.

The SKY73420-11 has been designed for optimum long-term reliability. The SKY73420-11 diversity downconversion mixer is provided in a compact, 36-pin Quad Flat No-Lead (QFN) package.
