AN RFMD® APPLICATION NOTE RFPA2189 Typical Performance for Multiple Application Circuits The RFPA2189 is a 0.5W SOT-89 power amplifier (PA) specifically designed for wireless infrastructure applications. It is a single-stage GaAs HBT PA offering ultra-linear operation at a comparably low DC power, making it ideal for next-generation radios requiring high efficiency and using single 5V power supplies. It is also ideal as a GaAs pre-driver for base station amplifiers, as a PA stage for commercial wireless infrastructure, as a 2nd or 3rd Stage LNA, and as a class AB operation for GSM, DCS, PCS, UMTS, WiMAX, and LTE transceiver applications. The RFPA2189 is capable of operating in bands such as 390MHz to 420MHz, 470MHz to 608MHz, 614MHz to 698MHz, 1805MHz to 1880MHz, and 1930MHz to1990MHz) Its external matching allows for use across various radio platforms within 400MHz to 2700MHz. The following performance data for multiple application circuits was collected under normal operation conditions (room temperature and supply voltage 5V).
