AP2085
5 GHz Power Amplifier
AP2085 is a linear, three-stage power amplifier MMIC in the
• Full 11a frequency range: 4.9~5.85GHz
5GHz band utilizing InGaP/GaAs HBT process. With the
(Gain and Power Flatness for the full 11a band)
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
Under Vc = 3.3V (For bias condition, please see
Application Note)
• High Gain: ~30dB at Pout=18dBm
• Pout @ EVM<3%: ~18dBm
• Total Current at Pout @ EVM<3%: ~210mA
suitable for the high gain applications in the full 802.11a
5GHz band.(4.9~5.85GHz)
Under Vc = 5V (For bias condition, please see
Application Note)
• High Gain: ~31dB at Pout=20dBm
• Pout @ EVM<3%: ~20dBm
• Total Current at Pout @ EVM<3%: ~260mA
