The HMC408LP3 power amplifier is a highly efficient 5.1 to 5.9 GHz GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC power amplifier with +30 dBm P1dB output power and +43 dBm output IP3. This PA is ideal for low cost UNII PT-PT/Multi-PT and 802.11a/HiperLAN WLAN access point applications. The power amplifier provides 20 dB of gain and +32.5 dBm of saturated power at 27% PAE from a single +5.0 V supply. A Power Down (Vpd) input provides RF output power and DC current control. The input of the amplifier is internally matched to 50 ohms and requires minimal external output matching components. The component comes in a low cost, leadless 3 × 3 mm surface mount package.
