General Description
Features

Conversion Loss: 15 dB
Fo, 3Fo, 4Fo Isolation: 40 dB
Input Drive Level: 10 to 20 dBm
Electrical Specications, TA = +25° C, As a Function of Drive Level
Typical Applications
The HMC187AMS8(E) is ideal for:
• Wireless Local Loop
• LMDS, VSAT, and Point-to-Point Radios
• UNII & HiperLAN
• Test Equipment
The HMC187AMS8(E) is a miniature frequency dou-
bler MMIC in plastic 8-lead MSOP package. The sup-
pression of undesired fundamental and higher order
harmonics is 40 dB typical with respect to input signal
levels. The doubler uses the same diode/balun tech-
nology 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 pas-
sive Schottky diode doubler technology contributes no
measurable additive phase noise onto the multiplied
signal.
