Description
The SKY73084-11 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 SKY73084-11 features an input IP3 of +25.2 dBm and a
Noise Figure (NF) of 9.4 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.
The SKY73084-11 is manufactured using a robust silicon BiCMOS
process and has been designed for optimum long-term reliability.
The SKY73084-11 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.
