Generꢀl Deꢁcription
The HMC519LC4 is a high dynamic range GaAs
pHEMT MMIC Low Noise Amplifier (LNA) housed in
a leadless 4 x 4 mm ceramic surface mount package.
The amplifier operates between 18 and 31 GHz,
providing 14 dB of small signal gain, 3.5 dB noise
figure and output IP3 of +23 dBm, while requiring only
75 mA from a +3V single supply. The P1dB output
power of +11 dBm, enables the LNA to function as a
LO driver for balanced, I/Q or image reject mixers. The
HMC519LC4 also features I/Os that are DC blocked
and internally matched to 50 Ohms, making it ideal for
microwave radio and VSAT applications.
