Description
The SKY73022-11 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 SKY73022-11 features an input IP3 of 26.5 dBm and a Noise
Figure (NF) of 9.8 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 55 dB of isolation between LO
inputs and supports the switching time required for GSM/EDGE
base stations.
The SKY73022-11 is manufactured using a robust silicon BiCMOS
process and has been designed for optimum long-term reliability.
The SKY73022-11 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.
