General Description
The HMC409LP4 & HMC409LP4E are high efficiency
GaAs InGaP HBT MMIC Power amplifiers operating
from 3.3 to 3.8 GHz. The amplifier is packaged in a
low cost, leadless SMT package. Utilizing a minimum
of external components the amplifier provides 31 dB
of gain and +32.5 dBm of saturated power from a
+5V supply voltage. The power control (Vpd) can be
used for full power down or RF output power/current
control. For +22 dBm OFDM output power (64 QAM,
54 Mbps), the HMC409LP4 & HMC409LP4E achieve
an error vector magnitude (EVM) of 2%, meeting
WiMAX 802.16 linearity requirements.
