| 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 * RFLGATM (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 4 10 -45 +45 RF OUT VCC 5 6 7 8 9 GND VCC GND QSIG C1299 PD RF QREF C1298 Figure 1.

Paths to ground should be made as short as possible. 2. The downset paddle of the SKY73010 direct quadrature modulator has special electrical and thermal grounding requirements. This pad is the main thermal conduit for heat dissipation. Since the circuit board acts as the heat sink, it must shunt as much heat as possible from the device. As such, design the connection to the ground pad to dissipate the maximum wattage produced to the circuit board. Multiple vias to the grounding layer are required. 3. Two external output bypass capacitors are required on the VCC pin. The values of these capacitors change with respect to the desired RF frequency. One capacitor should be used for low frequency bypassing and the other capacitor for high frequency bypassing. Special attention should be given so that the smaller value capacitor does not go into selfresonance at the desired RF frequency. Package and Handling Information Since the device package is sensitive to moisture absorption, it is baked and vacuum packed before shipping. Instructions on the shipping container label regarding exposure to moisture after the container seal is broken must be followed. Otherwise, problems related to moisture absorption may occur when the part is subjected to high temperature during solder assembly. The SKY73010 is rated to Moisture Sensitivity Level 3 (MSL3) at 260 C. It can be used for lead or lead-free soldering. For additional information, refer to the Skyworks Application Note, PCB Design & SMT Assembly/Rework Guidelines for RFLGA Packages, document number 103147. Care must be taken when attaching this product, whether it is done manually or in a production solder reflow environment. Production quantities of this product are shipped in a standard tape and reel format. For packaging details, refer to the Skyworks Application Note, Tape and Reel, document number 101568. Electrical and Mechanical Specifications The absolute maximum ratings of the SKY73010 are provided in Table 2. The recommended operating conditions are specified in Table 3 and electrical specifications are provided in Table 4. Typical performance characteristics are shown in Figures 3 through 7. Figure 8 provides a typical evaluation board schematic. Package dimensions for the 16-pin RFLGA are shown in Figure 9, and tape and reel dimensions are shown in Figure 10. Testing Procedure The following In-Phase and Quadrature (I/Q) input settings were used to measure the CDMA Adjacent Channel Power Reduction (ACPR): * Pilot Channel Active * Sync Channel Active * Paging Channel Active * Six Traffic Channels Active * 32x oversampling * Equifilter Electrostatic Discharge (ESD) Sensitivity The SKY73010 is a static-sensitive electronic device. Do not operate or store near strong electrostatic fields. Take proper ESD precautions.
