General Description
The HMC189MS8 is a miniature passive
frequency doubler in a plastic 8-lead MSOP
package. The suppression of the undesired
fundamental and higher order harmonics is
typically 40 to 45 dB with respect to input
signal levels. The doubler uses same diode/balun structures used in Hittite MMIC
mixers. The doubler is ideal for high volume
applications where frequency doubling of a
lower frequency is more economical than
directly generating a higher frequency. The
passive Schottky diode doubler technology
contributes no measurable additive phase
noise onto the multiplied signal. The
HMC189MS8 is ideal for 5.2 UNII, 5.8 ISM,
microwave radio and VSAT applications.
