General Description
Features
Functional Diagram
The HMC519LC4 is a high dynamic range GaAs
pHEMT MMIC Low Noise Amplier (LNA) housed in
a leadless 4 x 4 mm ceramic surface mount package.
The amplier operates between 18 and 31 GHz,
providing 14 dB of small signal gain, 3.5 dB noise
gure 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.

List of Material for Evaluation PCB 119667 [1]
The circuit board used in this application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground
leads and exposed paddle should be connected
directly to the ground plane similar to that shown.
A sufficient number of via holes should be used to
connect the top and bottom ground planes. The
evaluation board should be mounted to an appro-
priate heat sink. The evaluation circuit board shown
is available from Analog Devices, upon request.
