DATA SHEET SKY65170-21: 860 – 960 MHz, 0.5 W High Power Power Amplifier Applications Description • CDMA2000 cellular band Skyworks SKY65170-21 is a fully-matched, 0.5 W Power Amplifier (PA) with high efficiency, designed for use in the 860 to 960 MHz band. • Single DC supply: 5 V • Internal RF match and bias circuits • PA on/off control voltage • Small footprint, MCM (20-pin, 6 x 6 mm) SMT package (MSL3, 260 °C per JEDEC J-STD-020) Skyworks Pb-free products are compliant with all applicable legislation. For additional information, refer to Skyworks Definition of Lead (Pb)-Free, document number SQ04-0073. The primary bias to the SKY65170-21 can be supplied directly from a single 5 VDC supply. The PA is designed to operate with lower current by reducing the bias voltage. The device is internally matched and mounted in a 20-pin, 6 x 6 mm Multi-Chip Module (MCM) Surface-Mounted Technology (SMT) package, which allows for a highly manufacturable low cost solution. The device package and pinout for the 20-pin MCM are shown in Figure 1. A block diagram of the SKY65170-21 is shown in Figure 2.

A schematic diagram of the SKY65170-21 Evaluation Board is shown in Figure 8. An assembly drawing for the Evaluation Board is shown in Figure 9 and the layer detail is provided in Figure 10. The layer detail physical characteristics are noted in Figure 11. Since the device package is sensitive to moisture absorption, it is baked and vacuum packed before shipping. 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 SKY65170-21 is rated to Moisture Sensitivity Level 3 (MSL3) at 260 °C. It can be used for lead or lead-free soldering. For additional information, refer to Skyworks Application Note, PCB Design and SMT Assembly/Rework Guidelines for MCM-L Packages, document number 101752.
