SKY73020-11

700 – 1000 MHz High Gain and Linearity Diversity Downconversion Mixer for 2G/3G Base Station Transceiver Applications

Please note: SKY73020-11 is being discontinued and is not recommended for new designs.

The SKY73020-11 is a fully integrated diversity mixer that includes Local Oscillator (LO) drivers, an LO switch, 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 SKY73020-11 features an input IP3 of +27.0 dBm and a Noise Figure (NF) of 10.2 dB, making the device an ideal solution for high dynamic range systems such as 2G/3G base station receivers. The LO switch provides more than 65 dB of isolation between LO inputs and supports the switching time required for GSM/EDGE base stations.

The SKY73020-11 is manufactured using a robust silicon BiCMOS process and has been designed for optimum long-term reliability. The SKY73020-11 diversity downconversion mixer is provided in a compact, 36-pin 6 x 6 mm Multi-Chip Module (MCM).
