Functional Diagram
General Description
Saturated Power: +26 dBm @ 23% PAE
The HMC498LC4 is a high dynamic range GaAs
PHEMT MMIC Medium Power Amplifier housed in a
leadless “Pb free” SMT package. Operating from 17
to 24 GHz, the amplifier provides 22 dB of gain, +26
dBm of saturated power and 23% PAE from a +5V
supply voltage. Noise figure is 4 dB while output IP3 is
+36 dBm typical enabling the HMC498LC4 to function
as a low noise front end as well as a driver amplifier.
The RF I/Os are DC blocked and matched to 50 Ohms
for ease of use. The HMC498LC4 eliminates the
need for wire bonding, allowing use of surface mount
manufacturing techniques.

[1] Reference this number when ordering complete evaluation PCB
[2] Circuit Board Material: Rogers 4350.
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 appropriate heat sink. The evaluation circuit board shown
is available from Analog Devices, upon request.
