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
operating 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 +5.0V @ 74 mA. Input
and output 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 2.0 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.
