Description
The SKY73020 is a fully integrated diversity mixer that includes
Local Oscillator (LO) drivers, an LO switch, high linearity mixers,
and large dynamic range IF amplifiers. Low loss RF baluns have
also been included to reduce design complications and lower
system cost.
The SKY73020 features an input IP3 of 26 dBm and a Noise
Figure (NF) of 10 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 SKY73020 is manufactured using a robust silicon BiCMOS
process and has been designed for optimum long-term reliability.
The SKY73020 diversity downconversion mixer is provided in a
compact, 36-pin Multi-Chip Module (MCM). A functional block
diagram of the device is shown in Figure 1. Table 1 presents a
performance overview.
Skyworks offers lead (Pb)-free "environmentally
friendly" packaging that is RoHS compliant
(European Parliament for the Restriction of
Hazardous Substances).
