HMC498LC4
GaAs PHEMT MEDIUM
POWER AMPLIFIER, 17 - 24 GHz
Features
Output IP3: +36 dBm
Saturated Power: +26 dBm @ 23% PAE
Gain: 22 dB
+5V @ 250 mA Supply
50 Ohm Matched Input/Output
RoHS Compliant 4x4 mm SMT Package
General Description
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.
