Typical Applications
This HMC504LC4B is ideal for:
• Point-to-Point Radios
• Point-to-Multi-Point Radios
• Military & Space
• Test Instrumentation
The HMC504LC4B is a GaAs MMIC Low Noise
Wideband Amplifier housed in a leadless 4x4 mm cer-
amic surface mount package. The amplifier operates
between 14 and 27 GHz, providing up to 19 dB of
small signal gain, 2.2 dB noise figure, and output IP3
of +26 dBm, while requiring only 90 mA from a +4V
supply. The P1dB output power of up to +17 dBm
enables the LNA to function as a LO driver for balan-
ced, I/Q or image reject mixers. The HMC504LC4B
also features I/Os that are DC blocked and internally
matched to 50 Ohms, making it ideal for high capacity
microwave radios or VSAT applications. This versatile
LNA is also available in die form as the HMC-ALH476.

PCB [2] 122787 Evaluation PCB [3]
[1] Reference this number when ordering complete evaluation PCB
[2] Circuit Board Material: Rogers 4350 or Arlon 25FR
[3] Due to the very high frequency operation of this
product a custom LC4B PCB footprint and solder stencil
are required for this design. Performance shown in this data
sheet was produced using this custom footprint. DO NOT
USE Hittite’s standard LC4B footprint. Please contact
Applications for details.
List of Materials for Evaluation PCB 122789 [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.
