The SKY73049-350LF features a power gain of 7 dB, a 3rd Order Input Intercept Point (IIP3) of +26 dBm, and a Noise Figure (NF) of 15 dB over a wide frequency range, which makes the device an ideal solution for multi-band 2G, 2.5G, 3G, and 4G base station transceivers. The SKY73049-350LF is manufactured using a robust SiGe BiCMOS process, and has been designed for optimum long-term reliability. The device is provided in a compact, 3 x 3 mm, 16-pin Quad Flat No-Lead (QFN) package. 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. GND_MIX 5 Description S1697 Figure 2.

Technical Description Electrical and Mechanical Specifications The SKY73049-350LF is a high dynamic range single mixer, optimized for base station receiver applications. The device consists of an RF input stage, a high linearity active mixer core, and an LO amplifier. The absolute maximum ratings of the SKY73049-350LF are provided in Table 2. The recommended operating conditions are specified in Table 3, and electrical specifications are provided in Tables 4 (+5 V operation) and 5 (+3.3 V operation). RF Active Mixer Evaluation Board Description The high linearity SKY73049-350LF is an active, double balanced mixer that provides good noise performance and an excellent IIP3. Additionally, the balanced nature of the mixer provides for high port-to-port isolation. A wideband match to 50 Ω is provided internally, which eliminates the need for any external matching components except for a coupling capacitor. The SKY73049-350LF Evaluation Board is used to test the performance of the SKY73049-350LF downconversion mixer. An Evaluation Board schematic diagram is provided in Figure 3. An assembly drawing for the Evaluation Board is shown in Figure 4 and the layer detail is provided in Figure 5. The IF outputs are designed for 200 Ω differential impedance and require off-chip matching. Package Dimensions LO Buffers The LO buffers allow the input power of the SKY73049-350LF to be in the range of –10 to 0 dBm. The LO input frequency range is optimized for 200 to 5000 MHz, and could drive the mixer with both low-side and high-side LO injection. The single-ended LO port is internally matched to 50 Ω without the need for any external components. IF Output The SKY74039 has differential, high impedance open collector outputs (IF_OUT_N and IF_OUT_P) that need to be pulled up to supply voltage through RF chokes or through the center tap of a balun. The IF load for the mixer is provided externally. This flexible configuration enables the user to apply any external load, making IF_OUT_N and IF_OUT_P “broadband” outputs. The nominal value of this load is 200 Ω differential. Typical part markings are shown in Figure 6. Package dimensions for the 16-pin QFN are shown in Figure 7, and tape and reel dimensions are provided in Figure 8. Package and Handling Information 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. THE SKY73049-350LF is rated to Moisture Sensitivity Level 1 (MSL1) at 260 C. It can be used for lead or lead-free soldering. 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.

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. Note 2: Nominal thermal resistance (junction to case) is 5.1 C/W. Note 3: Applies to RF signal lines > 100 MHz, analog and RF lines < 100 MHz, digital lines, power supply lines, and ground pins. 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.
