| TQM7M5005 Advance Data Sheet GSM/EDGE Multi-mode Power Amplifier Module Functional Block Diagram Features DCS / PCS In DCS / PCS Out Mode Select Band Select VBATT VRAMP TX_EN Power Control Logic GSM 850 / 900 In GSM 850 / 900 Out Product Description The TQM7M5005 is an extremely small (5x5x1.0mm3) multi-mode power amplifier module for GSM/EDGE applications. This module has been optimized for high EDGE efficiency and EDGE power class E2 operation while maintaining high GSM/GPRS efficiency. In EDGE mode, the Vramp pin provides a continuously variable bias control to minimize current consumption during backed-off power conditions. The module incorporates two highly integrated InGaP power amplifier die with a CMOS controller. The CMOS controller implements a fully integrated closed-loop power control within the module for GSM Operation. This eliminates the need for any external couplers, power detectors, current sensing etc., to assure the output power level. The latter is set directly from the Vramp input from the DAC. The module has Tx enable, band select, mode (EDGE or GSM) inputs. Module construction is a low-profile over-molded land-grid array on laminate. * Very compact size - 5x5x1.0 mm3. * High GSM efficiency - GSM 850 55%, GSM900 55%, DCS 49%, PCS 49%. * High EDGE efficiency - GSM 850 24%, GSM 900 24%, DCS 25%, PCS 25% * Positive supply voltage - 3.0 to 4.5 V * 50 input and output impedances * GPRS class 12. * CMOS band select and internal closed-loop power control for GSM Operation. * High-reliability InGaP technology. * Ruggedness 10:1 * No external Vref Required Applications * * GSM/EDGE handsets GSM/EDGE wireless cards & data links Package Style Electrical Specifications Parameter GSM Pout Efficiency Pin EDGE Pout Efficiency Gain ACPR (400KHz) 850 Band Typ 35 55 3 28.5 24 32 62 900 Band Typ 35 55 3 28.5 24 32 62 DCS Band Typ 33 49 3 28 25 34 62 PCS Band Units Typ 33 dBm 49 % 3 dBm 28 dBm 25 % 34 dB 62 dBc RFIN_DCS MODE BS Package Size: LGA 5 x 5 x 1.0 mm Top View RFOUT_DCS VBATT Ground VRAMP TX_EN RFIN_GSM RFOUT_GSM For additional information and latest specifications, see our website: www.triquint.com Revision C, January 25, 2008 Advance Data Sheet: Subject to change without notice 1 |
