Typical Applications
The HMC156AC8 is suitable for:
• Wireless Local Loop
• LMDS, VSAT, and Point-to-Point Radios
• UNII & HiperLAN
• Test Equipment
The HMC156AC8 is a miniature frequency doubler in
a non-hermetic ceramic surface mount package. Sup-
pression of undesired fundamental and higher order
harmonics is 38 dB typical with respect to input signal
levels. The doubler uses the same diode/balun tech-
nology used in Hittite MMIC mixers, features small
size and requires no DC bias.

U1 HMC156AC8, Doubler
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 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. The evaluation circuit board
shown is available from Hittite upon request.
