3.5V AMPS/CDMA PA Module
RMPA0959 October 2004 RMPA0959 CDMA and CDMA2000-1X PowerEdge™ Power Amplifier Module General Description Features The RMPA0959 power amplifier module (PAM) is designed • Single positive-supply operation with low power and for cellular band AMPS, CDMA and CDMA2000-1X shutdown modes applications. The 2 stage PAM is internally matched to 50Ω • 39% CDMA efficiency at +28dBm average output power to minimize the use of external components and features a • 53% AMPS mode efficiency at +31dBm output power low-power mode to reduce standby current and DC power consumption during peak phone usage. High power-added • Compact LCC package ( 4.0 X 4.0 x 1.5 mm) efficiency and excellent linearity are achieved using our • Internally matched to 50Ω and DC blocked RF input/ Heterojunction Bipolar Transistor (HBT) process. output • Meets CDMA2000-1XRTT performance requirements Device Functional Block Diagram PA MODULE GND Vcc1 COLLECTOR (3, 7, 9,10,11) (5) BIAS 1 INTERSTAGE MATCH INPUT OUTPUT RF IN RF OUT INPUT OUTPUT MATCHING MATCHING (4) (8) MMIC STAGE STAGE NETWORK NETWORK INPUT STAGE OUTPUT STAGE VCC=3.4V (nom) BIAS BIAS VREF=2.85V (nom) 824-849 MHz 50Ω I/O COLLECTOR Vref BIAS CONTROL Vcc2 BIAS 2 (1) (6) Vmode (2) ©2004 RMPA0959 Rev.
