Description

AP2085 is a linear, three-stage power amplifier MMIC in the 5GHz band utilizing InGaP/GaAs HBT process. With the excellent linearity performance, the device delivers ~18dBm linear output power for EVM<3%, and 30dB gain under 54Mbps OFDM (IEEE802.11a) modulation at 3.3V. AP2085 can also deliver ~20dBm linear output power for EVM<3%, and 31dB gain at 5.0 V. The AP2085 is housed in a 3 x 3 (mm), 16 pin, QFN package. This power amplifier is suitable for the high gain applications in the full 802.11a 5GHz band.(4.9~5.85GHz)
