HMC368LP4 / 368LP4E
SMT GaAs PHEMT MMIC
AMP-DOUBLER-AMP, 9 - 16 GHz OUTPUT
v03.0705
General Description
Features
Functional Diagram
Output Power: +15 dBm
Wide Input Power Range: 0 to +10 dBm
100 kHz SSB Phase Noise: -140 dBc/Hz
+5V @ 75 mA Supply
16 mm2 Leadless QFN SMT Package
Electrical Speci cations, TA = +25° C, Vd1 = Vd2 = +5.0 Vdc, +2 dBm Drive Level
Typical Applications
• Microwave Radios & VSAT
• Fiber Optic Infrastructure
• Military Communications & Radar
The HMC368LP4 & HMC368LP4E are miniature
amp-doubler-amps utilizing GaAs PHEMT technology
in 4 x 4 mm leadless surface mount packages. When
driven by a +2 dBm signal, the multiplier provides
+15 dBm typical output power from 9 to 16 GHz. The
Fo and the 3Fo isolations are 18 dB typical. The low
additive SSB phase noise of -140 dBc/Hz at 100 kHz
offset helps the user maintain good system noise
performance. The HMC368LP4(E) is ideal for use
in LO multiplier chains allowing reduced parts count
vs. traditional approaches.
