Description

The SKY73023 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 SKY73023 features an input IP3 of 25.5 dBm and a Noise

Figure (NF) of 9.5 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 45 dB of isolation between LO

inputs and supports the switching time required for GSM/EDGE

base stations.

The SKY73023 is manufactured using a robust silicon BiCMOS

process and has been designed for optimum long-term reliability.

The SKY73023 diversity downconversion mixer is provided in a

compact, 36-pin 6 x 6 mm Multi-Chip Module (MCM). A functional

block diagram is shown in Figure 1. The pin configuration and

package are shown in Figure 2. Signal pin assignments and

functional pin descriptions are provided in Table 1.
