General Description
Features
Functional Diagram
Electrical Specications, TA = +25° C, Vdd1, Vdd2 = +5V, +4 dBm Drive Level
Typical Applications
The HMC814LC3B is ideal for:
• Clock Generation Applications:
SONET OC-192 & SDH STM-64
• Point-to-Point & VSAT Radios
• Test Instrumentation
• Military & Space
• Sensors
The HMC814LC3B is a x2 active broadband frequ-
ency multiplier utilizing GaAs pHEMT technology
in a leadless RoHS compliant SMT package. When
driven by a +4 dBm signal, the multiplier provides
+17 dBm typical output power from 13 to 24.6 GHz.
The Fo, 3Fo and 4Fo isolations are >20 dBc at 19 GHz.
The HMC814LC3B is ideal for use in LO multiplier
chains for Pt-to-Pt & VSAT Radios yielding reduced
parts count vs. traditional approaches. The low ad-
ditive SSB Phase Noise of -136 dBc/Hz at 100 kHz
offset helps maintain good system noise perfor-
mance. The RoHS packaged HMC814LC3B elim-
inates the need for wire bonding, and allows the use of
surface mount manufacturing techniques.

[2] Circuit Board Material: Rogers 4350 or Arlon 25FR
The circuit board used in the application should
be generated with proper RF circuit design tech-
niques. Signal lines should have 50 Ohm imped-
ance 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 circuit board
shown is available from Hittite upon request.
