DATA SHEET SKY77589-21 Tx-Rx Quad-Band Front-End Module for GSM / GPRS (824-915 MHz) (1710-1910 MHz) w/ Six Linear TRx Switch Ports Applications Description • Quad-band cellular handsets encompassing - Class 4 GSM850 / GSM900 - DCS1800 / PCS1900 - Class 12 GPRS multi-slot operation - EDGE downlink compatible SKY77589-21 is a transmit and receive Front-End Module (FEM) with integrated power amplifier control designed in a low profile, compact form factor for quad-band cellular handsets comprising GSM850 / GSM900 and DCS1800 / PCS1900 operation. The SKY77589-21 offers a complete Transmit VCO-to-Antenna and Antenna-to-Receive SAW filter solution. The FEM also supports Class 12 General Packet Radio Service (GPRS) multi-slot operation and EDGE downlink. Features • High efficiency - 42% (GSM850) - 45% (GSM900) - 39% (DCS1800 / PCS1900) • Low transmit supply current - 1.35 A (GSM850) - 1.26 A (GSM900) - 0.92 A (DCS1800 / PCS1900) • 50 Ω matched Input/Output • Tx–VCO-to-antenna and antenna-to-Rx-SAW filter RF interface • RF switch affords high linearity, low insertion loss, and 0 V DC on Rx ports • Small, low profile package - 6 mm x 6 mm x 0.9 mm - 28-pad configuration The module consists of a GSM850 / GSM900 PA block and a DCS1800 / PCS1900 PA block, impedance-matching circuitry for 50 ohm input and output impedances, Tx harmonics filtering, high linearity / low insertion loss RF switch, and a Power Amplifier Control (PAC) block. One PA block supports the GSM850 / GSM900 bands and the other PA block supports the DCS1800 / PCS1900 bands. Both PA blocks share common power supply pads to distribute current. The output of each PA block and the outputs to the six receive pads are connected to the antenna pad through an RF switch. Six broadband interchangeable receive ports provide flexibility to support multimode and multiband configurations. The GaAs die, the CMOS die, the Switch die, and passive components are mounted on a multi-layer laminate substrate. The assembly is encapsulated with plastic overmold. Band selection and control of transmit and receive are performed using four external control pads. Refer to the block diagram in Figure 1 below. The band select pad, BS1, BS2, Mode, and TxEN select GSM850, GSM900, DCS, and PCS modes of operation. Transmit enable TxEN controls receive or transmit mode of the RF switch (Tx = logic 1). Proper timing between transmit enable TxEN and Analog Power Control VRAMP allows for high isolation between the antenna and Tx–VCO while the VCO is being tuned prior to the transmit burst. The SKY77589-21 is compatible with logic levels from 1.2 V to 2.9 V for BS1, BS2, MODE, and TxEN pads.

Table 10 lists the pad names and the associated signal descriptions. Figure 6 interprets typical case markings. Figure 6. Typical Case Markings Package Handling Information Because of its sensitivity to moisture absorption, this device package is baked and vacuum-packed prior to shipment. 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 SKY77589-21 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 Joint Industry Standard J-STD-020.
