RMPA0959 CDMA and CDMA2000-1X PowerEdge™ Power Amplifier Module www.DataSheet4U.com March 2006 RMPA0959 CDMA and CDMA2000-1X PowerEdge™ Power Amplifier Module Features ■ Single positive-supply operation with low power and shutdown modes ■ 39% CDMA efficiency at +28dBm average output power ■ 53% AMPS mode efficiency at +31dBm output power ■ Lead-free RoHS compliant 4 x 4 x 1.5mm leadless ■ Internally matched to 50Ω and DC blocked RF input/output ■ Meets CDMA2000-1XRTT performance requirements General Description The RMPA0959 power amplifier module (PAM) is designed for cellular band AMPS, CDMA and CDMA2000-1X applications. The 2 stage PAM is internally matched to 50Ω to minimize the use of external components and features a low-power mode to reduce standby current and DC power consumption during peak phone usage. High power-added efficiency and excellent linearity are achieved using our Heterojunction Bipolar Transistor (HBT) process.
