SKY73086: 650 – 900 MHz High Gain and Linearity Diversity
Downconversion Mixer
Applications
Description
The SKY73086 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.
• 2G/3G base station transceivers:
− GSM/EDGE, CDMA, UMTS/WCDMA
• Land mobile radio
• High performance radio links
The SKY73086 features an input IP3 of +24.4 dBm and a Noise
Figure (NF) of 11 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 60 dB of isolation between LO
inputs and supports the switching time required for GSM/EDGE
base stations.
Features
• Operating frequency range: 650 to 900 MHz
• IF frequency range: 100 to 500 MHz
• Conversion gain: 8.7 dB
The SKY73086 is manufactured using a robust silicon BiCMOS
process and has been designed for optimum long-term reliability.
The SKY73086 diversity downconversion mixer is provided in a
compact, 36-pin 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.
