www.DataSheet4U.com DATA SHEET SKY73010: 300 – 2500 MHz Direct Quadrature Modulator Applications QPSK/GMSK/QAM/DQPSK modulators Single-sideband modulators Image reject mixers CDMA base stations GSM/EDGE, TDMA/TDMA-EDGE, and Trans-European Trunked Radio (TETRA) base stations First upconverter in dual conversion receivers 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). Features Broad RF and LO frequency range: 300 to 2500 MHz Carrier suppression greater than 35 dBc Sideband suppression greater than 45 dBc Modulation bandwidth DC to 250 MHz Noise floor less than –153 dBm/Hz Broadband LO/RF flatness RFLGA™ (16-pin, 4 x 4 mm) Pb-free package (MSL3, 260 °C per JEDEC J-STD-020) QREF GND IREF ISIG QSIG 1 16 15 14 13 ISIG IREF GND 2 12 GND GND 3 11 GND LO LO ...
