Description
Skyworks SKY73009 is an integrated, broadband, high-dynamic
range quadrature demodulator for use in various wireless
communication system applications. The SKY73009 can perform
quadrature demodulation of RF input signals from 400 to
3000 MHz directly to baseband frequencies. The quadrature
outputs are differential and can be directly connected to most
commonly available A/D converters.
The high dynamic range and second order Input Intercept Point
(IIP2) value of the SKY73009 make it ideal for use in direct
conversion and low Intermediate Frequency (IF) receivers.
Figure 1 shows a functional block diagram for the SKY73009. The
device package and pinout for the 32-pin RF Land Grid Array
(RFLGA) are shown in Figure 2.
Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances) compliant packaging.
