SKY73009 functional block diagram 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 environmentally friendly packaging that is rohs compliant (european parliament for the restriction of hazardous substances). c1468 gnd gnd gnd vcc vcc vcc gnd gnd gnd 25 24 23 22 21 20 19 18 17 gnd gnd gnd gnd gnd lo gnd gnd gnd rf+ gnd gnd rfC gnd 10 11 12 13 14 15 16 32 31 30 29 28 27 26 gnd ifip gnd ifin gnd ifqp gnd ifqn gnd 1 2 3 4 5 6 7 8 9 figure 2.
