SKY12328-350LF-EVB 数据手册
DATA SHEET SKY12328-350LF: 0.5-4.0 GHz Five-Bit Digital Attenuator (0.5 dB LSB) Applications • Transceiver transmit automatic level control or receive automatic gain control in WiMAX, GSM, CDMA, WCDMA, WLAN, Bluetooth®, or Zigbee® land mobile radio base stations or terminal equipment • General-purpose signal attenuation in telecommunications and instrumentation applications Features • Broadband operation: 0.5 to 4.0 GHz • Attenuation range: 15.5 dB • LSB attenuation: 0.5 dB • Low insertion loss: 1 dB @ 900 MHz • Positive voltage operation: 2.7 to 5.5 V • Low current consumption: 500 MHz Exposure to maximum rating conditions for extended periods may reduce device reliability. 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.

Evaluation Board Description Package and Handling Information The SKY12328-350LF Evaluation Board is used to test the performance of the SKY12328-350LF digital attenuator. An assembly drawing for the Evaluation Board is shown in Figure 9 and an Evaluation Board schematic diagram is shown in Figure 10. 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. Package Dimensions THE SKY12328-350LF is rated to Moisture Sensitivity Level 1 (MSL1) at 260 °C. It can be used for lead or lead-free soldering. For additional information, refer to the Skyworks Application Note, Solder Reflow Information, document number 200164. Typical case markings are shown in Figure 11. Package dimensions for the 16-pin QFN are shown in Figure 12, and tape and reel dimensions are provided in Figure 13. 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.
