描述 Description

Please note: SKY73085-11 is being discontinued and is not recommended for new designs. Please note: SKY73085-11 is being discontinued and is not recommended for new designs.

The SKY73085-11 is a fully integrated diversity mixer thatincludes Local Oscillator (LO) drivers, an LO switch, high linearitymixers, and large dynamic range Intermediate Frequency (IF)amplifiers. Low loss RF baluns have also been included to reducedesign complications and lower system cost.

The SKY73085-11 features an input IP3 of 24.9 dBm and a NoiseFigure (NF) of 9.3 dB, making the device an ideal solution for highdynamic range systems such as 2G/3G base station receivers.The LO switch provides more than 60 dB of isolation between LOinputs and supports the switching time required for GSM/EDGEbase stations.

The SKY73085-11 is manufactured using a robust silicon BiCMOSprocess and has been designed for optimum long-term reliability.The SKY73085-11 diversity downconversion mixer is provided ina compact, 36-pin Multi-Chip Module (MCM). A functional blockdiagram is shown in Figure 1. The pin configuration and packageare shown in Figure 2. Signal pin assignments and functional pindescriptions are provided in Table 1.
