Functional Diagram
General Description
The HMC457QS16G is a high dynamic range
GaAs InGaP Heterojunction Bipolar Transistor
(HBT) 1 watt MMIC power amplifier operating
between 1.7 and 2.2 GHz. Packaged in a miniature
16 lead QSOP plastic package, the amplifier gain
is typically 27 dB from 1.7 to 2.0 GHz and 25 dB
from 2.0 to 2.2 GHz. Utilizing a minimum number of
external components, the amplifier output IP3 can
be optimized to +45 dBm. The power control (Vpd)
can be used for full power down or RF output power/
current control. The high output IP3 and PAE makes
the HMC457QS16G an ideal power amplifier for
Cellular/3G base station & repeater applications.
