General Description
Features
Functional Diagram
The HMC517LC4 chip is a high dynamic range GaAs
PHEMT MMIC Low Noise Ampli er (LNA) housed in
a leadless “Pb free” RoHS compliant SMT package.
The HMC517LC4 provides 19 dB of small signal gain,
2.5 dB of noise  gure and has an output IP3 of
+23 dBm. The P1dB output power of +13 dBm enables
the LNA to also function as a LO driver for balanced,
I/Q or image reject mixers. The HMC517LC4 allows
the use of surface mount manufacturing techniques.
Noise Figure: 2.5 dB
Gain: 19 dB
OIP3: +23 dBm
Single Supply: +3V @ 67 mA
50 Ohm Matched Input/Output
RoHS Compliant 4 x 4 mm Package
Electrical Speci cations, TA = +25° C, Vdd 1, 2, 3 = +3V
Typical Applications

Evaluation PCB
List of Materials for Evaluation PCB 108537 [1]
The circuit board used in the  nal application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be con-
nected 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
appropriate heat sink. The evaluation circuit board
shown is available from Hittite upon request.
