Description
The SKY73021 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 SKY73021 features an input IP3 of 26.0 dBm and a Noise
Figure (NF) of 9.6 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 50 dB of isolation between LO
inputs and supports the switching time required for GSM/EDGE
base stations.
The SKY73021 is manufactured using a robust silicon BiCMOS
process and has been designed for optimum long-term reliability.
The SKY73021 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.
Skyworks offers lead (Pb)-free RoHS (Restriction of
RFA
Hazardous Substances) compliant packaging.
