The device consists of a low loss RF balun and high linearity passive mixer. The LO buffer allows the input power of the SKY73063-11 to be in the range of ±6 dBm. The LO section is optimized for high-side LO injection. However, each of the two LOs can be driven over a wide frequency range with some degradation in performance. An LO amplifier is also included that allow the SKY73063-11 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 (LO1 and LO2) for frequency hopping applications such as GSM. A high isolation SPDT switch allows the SKY73063-11 to be used for frequency hopping applications. This switch provides greater than 40 dB of LO1 to LO2 isolation: RF Balun and Passive Mixer The RF balun provides a single ended input, which can easily be matched to 50 Ω using a simple external matching circuit. The balun offers very low loss, and excellent amplitude and phase balance. The high linearity SKY73063-11 is a passive, double-balanced mixer that provides a very low conversion loss, and excellent 3rd Order Input Insertion Point (IIP3). Additionally, the balanced nature of the mixer provides for high port-to-port isolation. LO_SEL Input LO Path Selected High LO1 (pin 11) enabled Low LO2 (pin 15) 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. Electrical and Mechanical Specifications The absolute maximum ratings of the SKY73063-11 are provided in Table 2 and the recommended operating conditions in Table 3. Electrical characteristics for the SKY73063-11 are provided in Table 4. Typical performance characteristics of the SKY73063-11 are illustrated in Figures 3 through 14. Table 2.

There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. 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 15 and the layer detail is provided in Figure 16. 2. The ground pad of the SKY73063-11 provides critical electrical and thermal functionality. The connection to the ground pad should be designed to provide the best ground for the mixer. For more information on soldering the SKY7306311, refer to the Package and Handling Information section of this Data Sheet. Circuit Design Configurations 3. Skyworks recommends including external bypass capacitors on the VCC voltage inputs of the device. 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 and as low impedance as possible.
