Passive: no bias required
Available in an ultra small package: MSOP-8

The HMC204 devices are passive miniature frequency doublers that are available in a monolithic microwave integrated circuit (MMIC) die (HMC204), a nonhermetic surface mount package, and an 8-lead MSOP surface mount package. Suppression of undesired fundamental and higher order harmonics range from 38 dB to 42 dB typical with respect to input signal level. The doublers utilize the same GaAs Schottky diode/balun technology found in Hittite MMIC mixers. They feature small size, no dc bias, and no measurable additive phase noise onto the multiplied signal.
