... RF2131 Theory of Operat ion and Applicat ion Infor mat ion The RF2131 is a two-stage device with 25dB gain at full power. Therefore, for +31dBm output power, the drive required to fully saturate the output is +6dBm. Based upon HBT (Heterojunction Bipolar Transistor) 2 technology, the part requires only a single positive 4 ...

... High current conditions are also potentially dangerous to any RF device. High currents lead to high channel temperatures and may force early failures. The RF2131 includes temperature compensation circuits in the bias network to stabilize the RF transistors, thus limiting the current through the amplifier and protecting the devices from damage ...

... RF2131 Optimized for Efficiency at 4.8V VPC 100 100 100 pF This schematic defines the optimum configuration for maximum efficiency at 4.8V. Under these conditions, as can be seen in the data plots, the power drops at 4.0V. Over 70% power-added efficiency can be achieved at +30.8dBm with 4.8V and +8dBm input level with this implementation. ...
