HMC498LC4
v05.0418 LINEAR & POWER AMPLIFIERS -SMT GaAs PHEMT MEDIUM
POWER AMPLIFIER, 17 -24 GHz
Typical Applications Features The HMC498LC4 is ideal for use as a LNA or Driver
amplifier for: Output IP3: +36 dBm • Point-to-Point Radios Gain: 22 dB • Point-to-Multi-Point Radios & VSAT +5V @ 250 mA Supply • Test Equipment & Sensors 50 Ohm Matched Input/Output • Military End-Use RoHS Compliant 4x4 mm SMT Package 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. Electrical Specifications, TA = +25° C, Vdd1, 2, 3 = 5V, Idd = 250 mA*
