onsemi RF Amplifiers RMPA1765

The RMPA1765 is a power amplifier module designed for K-PCS, CDMA, CDMA2000-1X, and WCDMA applications, operating within a frequency range of 1720 to 1780 MHz. It features a compact lead-free compliant LCC package measuring 3.0 x 3.0 x 1.0 mm and is internally matched to 50 Ohms, which minimizes the need for external components. The amplifier achieves a power gain of 28 dB at +28 dBm output power with a power-added efficiency of 38% under CDMA/WCDMA conditions. This module supports single positive-supply operation and includes low power and shutdown modes to reduce power consumption during idle periods. It meets the performance requirements for CDMA2000-1XRTT and HSDPA, making it suitable for modern communication systems. The device operates with supply voltages of 5.0 V and a reference voltage range of 2.6 to 3.5 V. It also has a robust design, capable of withstanding load mismatches up to 10:1 without permanent damage. Engineers considering the RMPA1765 for their projects should note its high efficiency, compact size, and suitability for various PCS applications.
