Typical Applications

The HMC331 is a passive miniature frequency

doubler MMIC. Suppression of undesired fundamental

and higher order harmonics is 50 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, requires

no DC bias, and adds no measurable additive phase

noise onto the multiplied signal.

The HMC331 is suitable for:

• Wireless Local Loop

• LMDS, VSAT, and Point-to-Point Radios

• Test Equipment
