Description
Skyworks SKY73012 is an integrated, broadband, high-dynamic
range quadrature demodulator for use in various wireless
communication system applications. The SKY73012 can perform
quadrature demodulation of RF input signals from 400 to
3900 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 SKY73012 make it ideal for use in direct
conversion and low Intermediate Frequency (IF) receivers.
Figure 1 shows a functional block diagram for the SKY73012. 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.

Note 1: Differential IFI and IFQ output impedance without the use of a 9:1 impedance ratio balun.
Note 2: The recommended LO input power level can vary from –3 dBm to +3 dBm for the 900, 1900, and 2600 MHz RF input frequencies. Above 3300 MHz, better performance is achieved by
using a higher LO input power level such as +5 dBm.
Note 3: When a +5 dBm LO input power level is applied at 3600 MHz, the typical IIP2 value is 51 dBm and the typical IIP3 value is 22.5 dBm.
