4.9-5.9 GHZ HIGH-LINEARITY POWER AMPLIFIER

SST11CP15E is a versatile power amplifier designed for embedded applications and is based on the highly-reliable InGaP/GaAs HBT technology. It is easily configured for high-linearity, high-efficiency applications over a wide temperature range while operating over the 4.9-5.9 GHz frequency band. The SST11CP15E has excellent linearity while meeting 802.11a spectrum mask at 23 dBm with a 3.3V power supply, and at 24.5 dBm with a 5.0V supply. The power amplifier requires only a 4mA reference current for on/off control. It includes a VSWR/ temperature insensitive, linear power detector. The SST11CP15E is offered in a 12-contact UQFN package.
