SKY73009 Datasheet | Skyworks Solutions

Description Skyworks SKY73009 is an integrated, broadband, high-dynamic range quadrature demodulator for use in various wireless munication 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 monly 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, Ro HS (Restriction of Hazardous Substances) pliant packaging.
