DATA SHEET SKY65009-70LF: 100 to 2500 MHz Linear Power Amplifier Driver Applications Description Skyworks SKY65009-70LF is a high-performance, ultra-wideband UHF television, CATV, DBS power amplifier (PA) driver with superior output power, noise TETRA radio figure, linearity, and efficiency. The high linearity and superior GSM, GPRS, CDMA, WCDMA adjacent channel power rejection/adjacent channel leakage ratio (ACPR/ACLR) performance make the SKY65009-LF ideal for use in AMPS, PCS, DCS the driver stage of infrastructure transmit chains. ISM band transmitters The SKY65009-70LF is fabricated with Skyworks high-reliability Fixed WCS Aluminum (Al) Gallium Arsenide (GaAs) Heterojunction Bipolar WLAN and WiMAX Transistor (HBT) process, which allows for single-supply operation while maintaining high efficiency and good linearity. The device RFID uses low-cost surface-mount technology (SMT) in the form of a 2.4 x 4.5 mm small outline transistor (SOT-89) package. Features The module can operate over a temperature range of -40 C to Wideband frequency range: 100 to 2500 MHz +85 C. A populated Evaluation Board is available upon request.

The absolute maximum surface-mount package. The device operates with a single 3 V or ratings are provided in Table 2, and the recommended operating 5 V power supply connected though an RF choke (L1) to the conditions in Table 3. Electrical characteristics for the SKY65009 output pin. Capacitors C7, C8, and C9 provide DC bias decoupling are provided in Table 4. for VCC. Typical performance characteristics of the SKY65009 are The bias current is set by the on-chip active bias composed of illustrated in Figures 2 through 92. current mirror and reference voltage transistors, allowing for excellent gain tracking over temperature and voltage variations. The part is externally RF matched using surface mount Package and Handling Information components to facilitate operation over a frequency range of Instructions on the shipping container label regarding exposure to 100 MHz to 2500 MHz. moisture after the container seal is broken must be followed. Pin 1 is the RF input and pin 3 is the RF output. External DC Otherwise, problems related to moisture absorption may occur blocking is required for both input and output, but can be when the part is subjected to high temperature during solder implemented as part of the RF matching circuit. Pin 2 and the assembly. package backside metal, pin 4, provide the DC and RF ground. The SKY65009 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. Care must be taken when attaching this product, whether it is done manually or in a production solder reflow environment.
