LX5530RF/IF射频/中频RFID的射频放大器规格书PDF中文资料

DESCRIPTION

The LX5530 is a power amplifier optimized for the FCC Unlicensed National Information Infrastructure (U-NII) band, HyperLAN2 and Japan WLAN applications in the 4.9 – 5.9 GHz frequency range. The PA is implemented as a three-stage monolithic microwave integrated circuit (MMIC) with active bias, on-chip input matching and output pre-matching. The device is manufactured with an InGaP/GaAs Heterojunction Bipolar Transistor (HBT) IC process (MOCVD). It operates with a single positive voltage supply of 3 – 5V, with high power gain of up to 33dB. When operated at 5V supply voltage, it provides up to +25dBm linear output power for 802.11a OFDM spectrum mask compliance, and low EVM of 3 for up to +23dBm output power in the 4.9-5.9GHz band.
