Description
The SKY73021 is a fully integrated diversity mixer that includes Local Oscillator (LO) drivers, an LO switch, high linearity mixers, and large dynamic range Intermediate Frequency (IF) amplifiers. Low loss RF baluns have also been included to reduce design complications and lower system cost. The SKY73021 features an input IP3 of 26.0 dBm and a Noise Figure (NF) of 9.6 dB, making the device an ideal solution for high dynamic range systems such as 2G/3G base station receivers. The LO switch provides more than 50 dB of isolation between LO inputs and supports the switching time required for GSM/EDGE base stations. The SKY73021 is manufactured using a robust silicon BiCMOS process and has been designed for optimum long-term reliability. The SKY73021 diversity downconversion mixer is provided in a compact, 36-pin 6 x 6 mm Multi-Chip Module (MCM). A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1.

PRELIMINARY DATA SHEET * SKY73021 DOWNCONVERSION MIXER
Functional Description
The SKY73021 is a high gain diversity mixer, optimized for base station receiver applications. 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 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). 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 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. 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:

LO_SEL Input High Low
LO Path Selected LO1 (pin 19) enabled 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 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.

Evaluation Board Description
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. 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 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. Therefore, design the connection to the ground
pad to dissipate the maximum heat produced by the circuit board. For more information on soldering the SKY73021, 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 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. 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. A schematic diagram for the SKY73021 Evaluation Board is shown in Figure 38.
