GaAs PHEMT MMIC LOW NOISE
AMPLIFIER, 2 - 4 GHz
General Description
Features
Functional Diagram
The HMC594LC3B is a GaAs pHEMT MMIC Low
Noise Amplier (LNA) which operates from 2 to 4
GHz. The HMC594LC3B features extremely at
performance characteristics including 10 dB of small
signal gain, 3 dB of noise gure and output IP3 of
+36 dBm across the operating band. This high linearity
LNA is ideal for test & measurement equipment
and military assemblies due to its compact size,
consistent output power and DC blocked RF I/O’s.
The HMC594LC3B is also available in chip form as
the HMC594.
Gain Flatness: ±0.2 dB
Noise Figure: 3 dB
Gain: 10 dB
Output IP3: +36 dBm
DC Supply: +5V @ 95mA / +6V @ 100 mA
50 Ohm Matched Input/Output
RoHS Compliant 3x3 mm SMT package
Electrical Specications, TA = +25° C, Vdd = +5V, Idd = 95 mA, Vdd = +6V, Idd = 100mA*

Evaluation PCB
The circuit board used in the 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 Hittite upon request.
