General Description
The HMC755LP4E is a high gain, high linearity GaAs
InGaP HBT MMIC Power amplifier covering 2.3 to
2.8 GHz. The amplifier provides 31 dB of gain and
+33 dBm of saturated power from a single +5V
supply. The power control pins (VEN1, 2, 3) can be
used to reduce the RF output power/quiescent cur-
rent, or for full power down of the PA. The integrated
output power detector (VDET) is internally coupled
and requires no external components. For +25 dBm
OFDM output power (64 QAM, 54 Mbps), the HMC-
755LP4E achieves an error vector magnitude (EVM)
of only 2.5% making it ideal for WiMAX/LTE/4G Appli-
cations. The amplifier is packaged in a compact QFN
SMT package and requires a minimum of external
matching components.
