RMPA1759
Korean-PCS PowerEdge™ Power Amplifier Module
General Description
The RMPA1759 power amplifier module (PAM) is designed
for Korean 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 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 InGaP
Heterojunction Bipolar Transistor (HBT) process.
Features
• Single positive-supply operation and low power and
shutdown modes
• 38% 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
