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. The LO buffers allow the input power of the SKY73422-11 to be driven in the range of –6 to +6 dBm. The LO section has been optimized for center frequencies of 2100 to 2550 MHz. However, the LO can be driven over a wide frequency range with only slight degradation in performance. The SKY73422-11 also includes a power-down feature used to lower the supply current for standby operation (refer to Tables 4 and 5): PWRDN Logic: Mixer State: High Standby (low power mode) Low Full operation LO amplifiers are also included that allow the SKY73422-11 to connect directly to the output of a Voltage Controlled Oscillator (VCO). This eliminates the extra gain stages needed by most discrete passive mixers. 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 over a wide frequency range of 1700 to 2700 MHz. 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. Bandselect Logic Pins 17 (RLOB) and 29 (RLOA) allow for external biasing of the LO driver bias currents to trade off linearity for the core passive mixer current. Power-Down Mode The SKY73422-11 also includes a low current power-down mode controlled by pin 22 (PWRDN). When this pin is at a logic high level, the power-down function is enabled with the total mixer current under 45 mA. PWRDN does not have an internal pull-up or pull-down. IF Amplifier The SKY73422-11 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 impedance. The IF amplifiers are optimized for IF frequencies between 100 and 400 MHz. The IF amplifiers can be operated outside of this range, but with a slight degradation in performance. Pins 11 (RIFB) and 35 (RIFA) allow for external biasing of the IF amplifier bias currents to trade off linearity for the IF amplifier current. The SKY73422-11 is designed to optimize performance in four sub-bands. The particular sub-band of interest is selected by setting pin 24 (BS0) and pin 25 (BS1). The bandselect logic is provided in Table 2. Electrical and Mechanical Specifications Depending on the LO injection side, and the RF and IF frequencies involved, there could be multiple bandselect solutions. Table 5 identifies recommended bandselects for a number of frequency ranges. The absolute maximum ratings of the SKY73422-11 are provided in Table 3. The recommended operating conditions are specified in Table 4 and electrical specifications are provided in Tables 5 and 6. Table 2.

Exceeding any of the limits listed here may result in permanent damage to the device. CAUTION: Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.

An assembly drawing for the Evaluation Board is shown in Figure 3 and the layer detail is provided in Figure 4. A schematic diagram of the SKY73422-11 Evaluation Board is shown in Figure 5. It is recommended to apply solder paste with stencil, as noted in Figure 6. RF and IF matching components are listed in Table 7. Package Dimensions Circuit Design Considerations The PCB layout footprint for the SKY73422-11 is provided in Figure 6. Figure 7 shows the package dimensions for the 36-pin QFN, and Figure 8 provides the tape and reel dimensions. The following design considerations are general in nature and must be followed regardless of final use or configuration: Paths to ground should be made as short as possible. Package and Handling Information The ground pad of the SKY73422-11 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. 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. Skyworks recommends including external bypass capacitors on the VCC voltage inputs of the device. The SKY73422-11 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. Components L12, L13, L14, and L15 (see Figure 5) are high-Q low loss inductors. These inductors must be able to pass currents in excess of 200 mA DC. Components R8, R9, R31, and R35 (see Figure 5) allow for external adjustment of the IF amplifier bias currents. Skyworks recommends that these resistors have a tolerance of 1% to optimize performance consistency of the SKY73422-11. These resistors are optional for device operation. 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. Components R29, R33, R34, and R37 (see Figure 5) allow for external adjustment of the LO driver bias currents.
