The device consists of a low loss RF balun, high linearity passive mixer, and a low noise IF amplifier. An LO amplifier is also included that allow the SKY73033 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. 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 SKY73033 is a passive, double balanced mixer that provides a very low conversion loss, and excellent 3rd Order Input Insertion Point (IIP3). Addtionally, 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 SKY73033 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. A high isolation SPDT switch allows the SKY73033 to be used for frequency hopping applications. This switch provides greater than 40 dB of LO1 to LO2 isolation: LO_SEL Input High Low LO Path Selected LO1 (pin 11) enabled 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. IF Amplifier The SKY73033 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 SKY73033 are provided in Table 2 and the recommended operating conditions in Table 3.

An assembly drawing for the Evaluation Board is shown in Figure 3 and the layer detail is provided in Figure 4. 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 and as low impedance as possible. 2. The ground pad of the SKY73033 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. Therefore, design the connection to the ground pad to dissipate the maximum heat produced by the circuit board. For more information on soldering the SKY73033, refer to the Package and Handling Information section of this Data Sheet. 3. Skyworks recommends including external bypass capacitors on the VCC voltage inputs of the device. 4. Components L3 and L4 (see Figure 5) are high-Q, low loss inductors. These inductors must be able to pass currents in excess of 200 mA DC. 5. Components R7 and R8 (see Figure 5) allow for external adjustment of the IF amplifier bias points. For operation as specified in Tables 3 and 4, these resistors are not required. A schematic diagram for the SKY73033 Evaluation Board is shown in Figure 5.
