SKY73020: 700 – 1000 MHz High Gain and Linearity Diversity
Downconversion Mixer for 2G/3G Base Station Transceiver
Applications
Applications
•
2G/3G base station transceivers:
−
GSM/EDGE, CDMA, UMTS/WCDMA, iDEN
•
Land mobile radio
•
ISM band transceivers
•
High performance radio links
•

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 Intermediate Frequency (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 27.0 dBm and a Noise
Figure (NF) of 10.2 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 65 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 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.
