HMC204C8
GaAs MMIC SMT PASSIVE FREQUENCY
DOUBLER, 4 - 8 GHz INPUT
General Description
Features
Functional Diagram
Conversion Loss: 16 dB
Fo, 3Fo, 4Fo Isolation: 40 dB
Passive: No Bias Required
Electrical Speci cations, TA = +25° C, As a Function of Drive Level
Typical Applications
The HMC204C8 is suitable for:
• Wireless Local Loop
• LMDS, VSAT, and Point-to-Point Radios
• Test Equipment
The HMC204C8 is a passive miniature frequency
doubler in a non-hermetic surface mount package.
Suppression of undesired fundamental and higher
order harmonics is 40 dB typical with respect to input
signal level. The doubler utilizes the same GaAs
Schottky diode/balun technology found in Hittite
MMIC mixers. It features small size, no DC bias, and
no measurable additive phase noise onto the multi-
plied signal.

PCB [2] 107165 Eval Board
[1] Reference this number when ordering complete evaluation PCB
[2] Circuit Board Material: Rogers 4350
The circuit board used in the  nal 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. The evaluation circuit
board shown is available from Hittite upon request.
