Functional Diagram
General Description
The HMC368LP4 & HMC368LP4E are miniature amp-
doubler-amps utilizing GaAs PHEMT technology in 4
mm 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 & HMC368LP4E are
ideal for use in LO multiplier chains allowing reduced
parts count vs. traditional approaches.
