General Description

Functional Diagram
Conversion Loss: 15 dB
Fo, 3Fo, 4Fo Isolation: 45 dB
Input Drive Level: 10 to 20 dBm
Electrical Speci cations, TA = +25° C, As a Function of Drive Level
Typical Applications
The HMC188MS8 / HMC188MS8E is suitable for:
• Wireless Local Loop
• LMDS, VSAT, and Point-to-Point Radios
• UNII & HiperLAN
• Test Equipment
The HMC188MS8 & HMC188MS8E are miniature
frequency doublers in plastic 8-lead MSOP packages.
The suppression of undesired fundamental and higher
order harmonics is 45 dB typical with respect to input
signal levels. The doubler uses the same diode/balun
technology 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.
