MULTIPLIER, 23 - 33 GHz
General Description
Features
Functional Diagram
Electrical Specications, TA = +25° C, Vdd1, Vdd2 = +5V, 3 dBm Drive Level
Typical Applications
The HMC578LC3B is suitable for:
• Clock Generation Applications:
SONET OC-192 & SDH STM-64
• Point-to-Point & VSAT Radios
• Test Instrumentation
• Military & Space
The HMC578LC3B is a x2 active broadband frequ-
ency multiplier utilizing GaAs PHEMT technology in a
leadless RoHS compliant SMT package. When driven
by a +3 dBm signal, the multiplier provides +15 dBm
typical output power from 23 to 33 GHz. The Fo and
3Fo isolations are >20 dBc and >30 dBc respectively
at 28 GHz. The HMC578LC3B is ideal for use in LO
multiplier chains for Pt-to-Pt & VSAT Radios yielding
reduced parts count vs. traditional approaches. The
low additive SSB Phase Noise of -129 dBc/Hz at
100 kHz offset helps maintain good system noise
performance. The RoHS packaged HMC578LC3B
eliminates the need for wire bonding, and allows the
use of surface mount manufacturing techniques.

Evaluation PCB
The circuit board used in the nal application
should be generated with proper RF circuit design
techniques. Signal lines should have 50 ohm
impedance 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.
