HMC204MS8G / 204MS8GE
GaAs MMIC SMT PASSIVE FREQUENCY
DOUBLER, 4 - 8 GHz INPUT
v05.0607
General Description
Features
Functional Diagram
Conversion Loss: 17 dB
Fo, 3Fo, 4Fo Isolation: 42 dB
Passive: No Bias Required
Ultra Small Package: MSOP8
Electrical Speci cations, TA = +25° C, As a Function of Drive Level
Typical Applications
The HMC204MS8G / HMC204MS8GE is suitable for:
• Wireless Local Loop
• LMDS, VSAT, and Point-to-Point Radios
• UNII & HiperLAN
• Test Equipment
The HMC204MS8G & HMC204MS8GE are passive
miniature frequency doublers in 8 lead MSOP surface
mount packages. Suppression of undesired funda-
mental and higher order harmonics is 42 dB typical
with respect to input signal level. The doubler utilizes
the same GaAs Schottky diode/balun technology
found in Hittite MMIC mixers. It requires no DC bias
and adds no measurable phase noise onto the multi-
plied signal.

The circuit board used in the nal application
should be generated with proper RF circuit design
techniques. Signal lines at the RF port should have
50 ohm impedance and the package ground leads
and exposed ground paddle should be connected
directly to the ground plane similar to that shown
above. The evaluation circuit board shown above is
available from Hittite Microwave Corporation upon
request.
