The device consists of two diversity channels, each consisting of a low loss RF balun, high linearity passive mixer, and a low noise IF amplifier. LO amplifiers are also included that allow the SKY73084-11 to connect directly to the output of a Voltage Controlled Oscillator (VCO). This eliminates the extra gain stages needed by most discrete passive mixers. A Single Pole, Double Throw (SPDT) switch has been included to select between two different LO inputs for frequency hopping applications (i.e., GSM). RF Baluns and Passive Mixer The RF baluns provide a single ended input, which can easily be matched to 50 Ω using a simple matching circuit. The RF baluns offer very low loss and excellent amplitude and phase balance. The high linearity mixer is a passive, double balanced mixer that provides a very low insertion loss, and excellent 3rd Order Input Insertion Point (IIP3) and linearity performance. Additionally, the balanced nature of the mixer provides for excellent port-to-port isolation. LO Buffers and SPDT LO Switch The LO buffers allow the input power of the SKY73084-11 to be programmed in the range of –6 to +6 dBm. The LO section has been optimized for high-side LO injection. However, the LO can be driven over a wide frequency range with only slight degradation in performance. A high isolation SPDT switch allows the SKY73084-11 to be used for frequency hopping applications. This switch provides greater than 60 dB of LO1 to LO2 isolation: LO_SEL Logic: High Low State: LO1 enabled LO2 enabled For applications that do not require frequency hopping, LO_SEL is fixed to one state and the appropriate LO input is used. IF Amplifier The SKY73084-11 includes high dynamic range IF amplifiers that follow the passive mixers in the signal path. The outputs require a supply voltage connection using inductive chokes. These choke inductors should be high-Q and have the ability to handle 200 mA or greater. A simple matching network allows the output ports to be matched to a balanced 200 Ω impedance. The IF amplifiers are optimized for IF frequencies between 50 and 250 MHz. The IF amplifiers can be operated outside of this range, but with a slight degradation in performance. Electrical and Mechanical Specifications The absolute maximum ratings of the SKY73084-11 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 of the SKY73084-11 are illustrated in Figures 3 through 31. Table 2.

Mixer B 4RF to 3LO vs Supply Voltage and Temperature Evaluation Board Description The SKY73084-11 Evaluation Board is used to test the performance of the SKY73084-11 downconversion mixer. An assembly drawing for the Evaluation Board is shown in Figure 32 and the layer detail is provided in Figure 33. A schematic diagram of the SKY73084-11 Evaluation Board is shown in Figure 34. Circuit Design Configurations The following design considerations are general in nature and must be followed regardless of final use or configuration: 1. Paths to ground should be made as short as possible. 2. The ground pad of the SKY73084-11 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. Therefore, design the connection to the ground pad to dissipate the maximum wattage produced by the circuit board. 3. Skyworks recommends including external bypass capacitors on the VCC voltage inputs of the device. 4. Components L5, L6, L14, and L15 (see Figure 34) are high-Q low loss inductors. These inductors must be able to pass currents in excess of 200 mA DC. 5. Components R1 and R2 (see Figure 34) set the bias current for the IF amplifiers. Skyworks recommends that these resistors have a tolerance of ±1% to optimize performance consistency of the SKY73084-11. These resistors are not required for the Evaluation Board to operate as specified in Tables 3 and 4. Package Dimensions The PCB layout footprint for the SKY73084-11 is provided in Figure 35. Figure 36 shows the package dimensions for the 36-pin MCM and Figure 37 provides the tape and reel dimensions. 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 SKY73084-11 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 MCM-L Packages, document number 101752. 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. Electrostatic Discharge (ESD) Sensitivity The SKY73084-11 is a static-sensitive electronic device. Do not operate or store near strong electrostatic fields. Take proper ESD precautions.
