SKY77318

DATA SHEET SKY77318 iPAC™ PAM for Quad-Band GSM / GPRS Applications • Quad-Band cellular handsets encompassing - Class 4 GSM850/900 - Class 1 DCS1800/ PCS1900 - Class 12 GPRS multi-slot operation Description The SKY77318 Power Amplifier Module (PAM) is designed in a low profile (1.2 mm), compact form factor for quad-band cellular handsets comprising GSM850/900, DCS1800, and PCS1900 operation. The PAM also supports Class 12 General Packet Radio Service (GPRS) multi-slot operation. The module consists of separate GSM PA and DCS1800/PCS1900 PA blocks, impedance-matching circuitry for 50 Ω input and output impedances and a Power Amplifier Control (PAC) block with an internal current-sense resistor. The custom BiCMOS integrated circuit provides the internal PAC function and interface circuitry. Fabricated onto a single Gallium Arsenide (GaAs) die, one Heterojunction Bipolar Transistor (HBT) PA block supports the GSM bands and the other supports the DCS1800 and PCS1900 bands. Both PA blocks share common power supply pads to distribute current. The GaAs die, the Silicon (Si) die, and the passive components are mounted on a multi-layer laminate substrate. The assembly is encapsulated with plastic overmold. RF input and output ports of the SKY77318 are internally matched to a 50 Ω load to reduce the number of external components for a quad-band design. Extremely low leakage current (2.5 μA, typical) of the dual PA module maximizes handset standby time. The SKY77318 also contains bandselect switching circuitry to select GSM (logic 0) or DCS/PCS (logic 1) as determined from the Band Select (BS) signal. In Figure 1 below, the BS pad selects the PA output (DCS/PCS_OUT or GSM_OUT) and the Analog Power Control (VAPC) controls the level of output power. The VBATT pad connects to an internal current-sense resistor and interfaces to an integrated power amplifier control (iPAC™) function, which is insensitive to variations in temperature, power supply, process, and input power. The ENABLE input allows initial turn-on of PAM circuitry to minimize battery drain.

Instructions on the shipping container label must be followed regarding exposure to moisture after the container seal is broken, otherwise, problems related to moisture absorption may occur when the part is subjected to high temperature during solder assembly. The SKY77318 is capable of withstanding an MSL3/260 °C solder reflow. Care must be taken when attaching this product, whether it is done manually or in a production solder reflow environment. If the part is attached in a reflow oven, the temperature ramp rate should not exceed 3 °C per second; maximum temperature should not exceed 260 °C. If the part is manually attached, precaution should be taken to insure that the part is not subjected to temperatures exceeding 260 °C for more than 10 seconds. For details on attachment techniques, precautions, and handling procedures recommended by Skyworks, please refer to Skyworks Application Note: PCB Design and SMT Assembly/Rework, Document Number 101752. Additional information on standard SMT reflow profiles can also be found in the JEDEC Standard J-STD–020. • Personnel Grounding - Wrist Straps - Conductive Smocks, Gloves and Finger Cots - Antistatic ID Badges • Protective Workstation - Dissipative Table Top - Protective Test Equipment (Properly Grounded) - Grounded Tip Soldering Irons - Solder Conductive Suckers - Static Sensors Production quantities of this product are shipped in the standard tape-and-reel format.

Electrostatic Discharge Sensitivity The SKY77318 has been classified as a Human Body Model Class 1C (1000 volts to < 2000 volts) and Machine Model Class M2 (100 volts to < 200 volts) device. ESD testing has been performed in compliance to the latest JEDEC Human Body Model specification, HBM (JESD22-A114-B) and Machine Model specification, (JESD22-A115-A). A report summarizing the ESD testing, including ESD failure level thresholds on each pad-toground and pad-to-pad combination, may be obtained upon request. To avoid ESD damage, both latent and visible, it is very important that the product assembly and test areas follow the Class-1 ESD handling precautions listed below. • Facility - Relative Humidity Control and Air Ionizers - Dissipative Floors (less than 109 Ω to GND) • Protective Packaging and Transportation - Bags and Pouches (Faraday Shield) - Protective Tote Boxes (Conductive Static Shielding) - Protective Trays - Grounded Carts - Protective Work Order Holders Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • sales@skyworksinc.com • www.skyworksinc.com 200424B • Skyworks Proprietary and Confidential Information • Products and product information are subject to change without notice. • December 17, 2007 15 DATA SHEET SKY77318 iPAC™ PAM FOR QUAD-BAND GSM / GPRS Technical Information Closed loop control of the amplifier is enabled when ENABLE is driven to logic high. The PA collector current will then be directly proportional to the VAPC input voltage over the range of 200 mV to 2.1 V. To meet the GSM power versus time mask and switching transient requirements the PAM must be provided with a DAC ramp profile on the VAPC input as well as proper timing on digital controls for the PAC circuitry. Note: Please refer to 3GPP TS 51.010-1: Mobile Station (MS) conformance specification. All GSM specifications are now the responsibility of 3GPP. The standards are available at http://www.3GPP.org. acceptable spectral limits at specified offset frequencies. The VAPC input has an internal reconstruction filter such that external resistors or capacitors are unnecessary on the phone board or the test fixture. Figure 7 represents the dynamic characteristics of the RF output burst power that results from the ramp profile delivered by the DAC to the VAPC input. The transmit power must not exceed the given limits at the time specified relative to the start and end of the data burst. Additional requirements are placed on spectral components generated by switching transients. Ramping at high rates will result in components that violate these spectral limits. A ramp control signal must be applied to the VAPC pad, which results in the desired power ramp response. The log relationship of VAPC to POUT, along with the finite bandwidth and potential slew rate limitations of the feedback loop, results in a complex mapping of the ramp profile to the actual output power. Careful attention is required in generating the input waveform which results in the desired output response. Figure 8 shows an example of the Skyworks PAM test setup for evaluation of RF performance with various ramp profiles. The user’s test setup may also include a TX/RX switch and a diplexer in the output signal path. Alternatively, the SKY77318 PAM may be installed in a phone board. The SKY77318 has been designed to comply with interface requirements and DAC resolution of leading base band devices. The ramp profile typically consists of a pedestal voltage, 10 to 16 discrete voltage steps on the rising edge of the burst, a constant region, 10 to 16 steps on the falling edge, and a final voltage. Typically, the user defines the start, stop, and 10 to 16 percentage values for each rising and falling edge, which are then applied as discrete voltages at the VAPC input. For the SKY77318, generally the same profile, scaled in amplitude, is used for all frequencies and power control levels. The ultimate purpose is to keep the RF output power ramp within the time mask and to maintain Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • sales@skyworksinc.com • www.skyworksinc.com 16 December 17, 2007 • Skyworks Proprietary and Confidential Information. • Products and product information are subject to change without notice. • 200424B SKY77318 iPAC™ PAM FOR QUAD-BAND GSM / GPRS DATA SHEET VBATT VCC1 BS TX_RX PAC_EN 17 μs Peak DAC Value 12 μs VAPC Pedestal Period Ramp Up Profile Ramp Down Profile Final Period 6 μs dB +4 +1 –1 –6 (2) 11 μs 9 μs 3μs (Trace Exaggerated For Clarity) (t) Output Power –30 (3) Ramp Up Pedestal Ramp Down Final Value (1) (t) 10 μs 8 μs 10 μs 542.8 μs Burst (147 bits) 10 μs 8 μs 10 μs (1) (2) For GSM For DCS1800 / PCS1900 For GSM –59 dBc or –36 dBm, whichever is higher. –48 dBc or –48 dBm, whichever is higher. –4 dBc for power control level 16, –2 dBc for power control level 17, –1 dBc for power control level 18 and 19. –4 dBc for power control level 11, –2 dBc for power control level 12, –1 dBc for power control level 13, 14, 15. –30 dBc or –17 dBm, whichever is higher. –30 dBc or –20 dBm, whichever is higher. 103237_008 For DCS1800 / PCS1900 (3) For GSM For DCS1800 / PCS1900 Figure 7.
