HMC188MS8 / 188MS8E v04.0709 FREQ. MULTIPLIERS - PASSIVE - SMT 7 GaAs MMIC SMT PASSIVE FREQUENCY DOUBLER, 1.25 - 3.0 GHz INPUT Typical Applications Features The HMC188MS8 / HMC188MS8E is suitable for: Conversion Loss: 15 dB • Wireless Local Loop Fo, 3Fo, 4Fo Isolation: 45 dB • LMDS, VSAT, and Point-to-Point Radios Input Drive Level: 10 to 20 dBm • UNII & HiperLAN • Test Equipment Functional Diagram General Description 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.
