Functional Diagram
General Description
The HMC669LP3(E) is a versatile, high dynamic range
GaAs MMIC Low Noise Amplifier that integrates a
low loss LNA bypass mode on the IC. The amplifier
is ideal for receivers and LNA modules operating be-
tween 1.7 and 2.2 GHz and provides 1.4 dB noise
figure, 17 dB of gain and +29 dBm IP3 from a single
supply of +5V @ 86mA. Input and output return losses
are excellent and no external matching components
are required. A single control line is used to switch
between LNA mode and a low loss bypass mode.
Failsafe topology also enables the LNA bidirectional
bypass path when no DC power is available.
