This module has been optimized for high EDGE efficiency and EDGE power class E2 operation while maintaining high GSM/GPRS efficiency. Two EDGE quiescent current states are provided to minimize current consumption during backed-off power settings. 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 overmolded land-grid array on laminate. Applications * * GSM/EDGE handsets GSM/EDGE wireless cards & data links Electrical Specifications (Nominal) Parameter Min 43 850 Band Typ Max 35.5 50 2 29 23 30.5 -62 32.0 -58 4 Min 34.5 45 0 28.5 20 30.0 900 Band Typ Max 35.5 52 2 29 23 31.5 -62 33.0 -58 4 Min 32.0 40/45 0 28 20 37/36 DCS / PCS Typ Max 33 46/50 2 28.5 25 38/37 40/39 -62 -58 4 Units dBm % dBm dBm % dB dBc GSM Pout 34.5 Efficiency Pin 0 EDGE Pout 28.5 Efficiency Gain ACPR (400KHz) 20 29 Package Style Package Size: LGA 7 x 7 x 1.1 mm Top View RF_in_DCS Ground Gnd BS Tx_En Ground Vbatt Mode Vramp Vbias (digital) RF_in_GSM Gnd Ground Vcc Ground RF_out_DCS RF_out_GSM For additional information and latest specifications, see our website: www.triquint.com Revision J, April 20, 2006 Preliminary Data Sheet: Subject to change without notice 1 |
