Functional Diagram
General Description
The HMC605LP3 / HMC605LP3E are versatile, high
dynamic range GaAs MMIC Low Noise Amplifiers that
integrate a low loss LNA bypass path on the IC. The
amplifier is ideal for WiBro & WiMAX receivers oper-
ating between 2.3 and 2.7 GHz and provides 1.1 dB
noise figure, 20 dB of gain and +31 dBm output IP3
from a single supply of +5V @ 74 mA. Input and out-
put return losses are 14 and 15 dB respectively with
no external matching components required. A single
control line (Vctl) is used to switch between LNA mode
and a low 2 dB loss bypass mode and reduces the
current consumption to 10 μA. The HMC605LP3 is
failsafe and will default to the bypass mode with no
DC power applied.
