Description
Skyworks SKY73001 direct conversion mixer is an integrated,
high-dynamic range, zero Intermediate Frequency (IF)
architecture down-converter for use in wireless communication
applications. High second and third order input intercept points
(IIP2 and IIP3, respectively) allow seamless integration into high
performance systems. The SKY73001 has a wide RF and Local
Oscillator (LO) frequency range of 2 to 3500 MHz.
Figure 1 shows a functional block diagram for the SKY73001. The
device package and pinout for the 32-pin RF Land Grid Array
(RFLGA) are shown in Figure 2.
Skyworks offers lead (Pb)-free 鈥渆nvironmentally
friendly鈥?packaging that is RoHS compliant
(European Parliament for the Restriction of
Hazardous Substances).
