DESCRIPTION
The AP503 uses a high reliability InGaP/GaAs HBT process technology and does not require any external matching components. The module operates off of a +12V supply and does not requiring any negative biasing voltages; an internal active bias allows the amplifier to maintain high linearity over temperature. It has the added feature of a +5V power down control pin. While the module has been tuned for optimal performance for Class AB applications, the quiescent current can also be adjusted for Class B applications through an external resistor. A low-cost metal housing allows the device to have a low thermal resistance and achieves over 100 years MTTF. All devices are 100% RF and DC tested. The AP503 is targeted for use as a driver or final stage amplifier in wireless infrastructure where high linearity and high power is required.
