RMPA1959
PCS 3.4V CDMA & CDMA2000-1X PowerEdge™ Power Amplifier Module
General Description
The RMPA1959 power amplifier module (PAM) is designed
for CDMA and CDMA2000-1X personal communications
system (PCS) applications. The 2 stage PAM is internally
matched to 50Ω to minimize the use of external
components and features advanced DC power
management to reduce current consumption during peak
phone usage. High power-added efficiency and excellent
linearity are achieved using our InGaP Heterojunction
Bipolar Transistor (HBT) technology.
Features
• Single positive-supply operation and low power and
shutdown modes
• 39% CDMA efficiency at +28dBm average output power
• Compact LCC package- 4.0 x 4.0 x 1.5 mm with industry
standard pinout
• Internally matched to 50Ω and DC blocked RF input/
output.
• Meets CDMA2000-1XRTT performance requirements
