Description
The SKY73010 is an integrated quadrature modulator for direct
modulation of high frequency Amplitude Modulated (AM), Phase
Modulated (PM), or compound carriers. A SiGe Bipolar
Complementary Metal Oxide Semiconductor (BiCMOS) process is
used to offer excellent linearity, noise floor, and carrier
suppression performance.
The device package and pinout for the 16-pin RF Land Grid Array
(RFLGA) are shown in Figure 1. Figure 2 shows a functional block
diagram for the SKY73010. Signal pin assignments and functional
pin descriptions are provided in Table 1.
Skyworks offers this part as a lead (Pb)-free
“environmentally friendly” package that is RoHS
compliant (European Parliament for the Restriction
of Hazardous Substances).
