Skyworks Solutions, Inc. 1700 – 2200 MHz High Gain and Linearity Diversity Downconversion Mixer With Power-Down Mode SKY73090-21

The SKY73090-21 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 SKY73090-21 features an input IP3 of +24.2 dBm and a Noise Figure (NF) of 9.4 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 40 dB of isolation between LO inputs and supports the switching time required for GSM/EDGE base stations. The SKY73090-21 is manufactured using a robust silicon BiCMOS process and has been designed for optimum long-term reliability. The SKY73090-21 diversity downconversion mixer is provided in a compact, 36-pin Multi-Chip Module (MCM).
