The device consists of two diversity channels (A and B), each consisting of a low loss RF balun, high linearity passive mixer, and a low noise IF amplifier. Two LO amplifiers (independent of channels A and B) are also included that allow the SKY73021 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 external matching circuit. The RF baluns offer very low loss, and excellent amplitude and phase balance. The high linearity SKY73021 is a passive, double balanced mixer that provides a very low conversion loss and an excellent 3rd Order Input Intercept Point (IIP3). Additionally, the balanced nature of the mixer provides for high port-to-port isolation. LO Buffers and SPDT LO Switch The LO buffers allow the input power of the SKY73021 to be in the range of ±3 dBm. The LO section is optimized for low-side LO injection. However, each of the two LOs can be driven over a wide frequency range with only slight degradation in performance. LO_SEL Input LO Path Selected High LO1 (pin 19) enabled Low LO2 (pin 27) enabled For applications that do not require frequency hopping, LO_SEL is fixed to one state and the appropriate LO input is used. An internal pull-down resistor enables the LO2 input. IF Amplifier The SKY73021 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 40 and 300 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 SKY73021 are provided in Table 2 and the recommended operating conditions in Table 3. Electrical characteristics for the SKY73021 are provided in Table 4. Typical performance characteristics of the SKY73021 are illustrated in Figures 3 through 35. A high isolation SPDT switch allows the SKY73021 to be used for frequency hopping applications. This switch provides greater than 50 dB of LO1 to LO2 isolation: Table 2.

For more information on soldering the SKY73021, refer to the Package and Handling Information section of this Data Sheet. The SKY73021 Evaluation Board is used to test the performance of the SKY73021 downconversion mixer. An assembly drawing for the Evaluation Board is shown in Figure 36 and the layer detail is provided in Figure 37. 3. Skyworks recommends including external bypass capacitors on the VCC voltage inputs of the device. 4. Components L5, L6, L14, and L15 (see Figure 38) are high-Q, low loss inductors. These inductors must be able to pass currents in excess of 200 mA DC. Circuit Design Configurations The following design considerations are general in nature and must be followed regardless of final use or configuration: 5. Components R1 and R2 (see Figure 38) allow for external adjustment of the IF amplifier bias points. For operation as specified in Tables 3 and 4, these resistors are not required. 1. Paths to ground should be made as short and as low impedance as possible. 2. The ground pad of the SKY73021 provides critical electrical and thermal functionality. 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.

Figure 40 shows the package dimensions for the 36-pin MCM, and Figure 41 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. 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 SKY73021 is a static-sensitive electronic device. Do not operate or store near strong electrostatic fields. Take proper ESD precautions. THE SKY73021 is rated to Moisture Sensitivity Level 3 (MSL3) at 260 °C. It can be used for lead or lead-free soldering.
