SKY73085-11 390 – 500 MHz High Gain and Linearity Diversity Downconversion Mixer for 2G/3G Base Station Transceiver Applications

The SKY73085-11 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 SKY73085-11 features an input IP3 of 24.9 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 base station receivers. The LO switch provides more than 60 dB of isolation between LO inputs and supports the switching time required for GSM/EDGE base stations.
