It features 3.5 V battery operation, and exceptional efficiency. The AP119-89 is designed to be stable over a temperature range of -40 to +85C and over a 10:1 output VSWR load. External matching is used for improved performance, flexibility, and multi-band operation. Absolute Maximum Ratings Quantity Amplifier Supply Voltage (VDS) Input RF Power (PIN) Duty Cycle Operating Temperature (TOP) Storage Temperature (TST) Value 10 V 17 dBm 50% -40 to +85C Output Matching Circuit The output match for the AP119-89 is provided externally in order to improve performance, reduce cost, and add flexibility. By making use of ceramic surface mount components with better Qs than GaAs matching elements, a lower loss matching network can be made. This lower loss results in higher power and efficiency for the amplifier. Also, by keeping these elements external the GaAs die size is reduced and the overall cost is less. This approach also permits the flexibility to tweak the amplifier for optimum performance at different powers, and/or frequencies. w w w .d ee sh ta a u. t4 om c Skyworks Solutions, Inc.
