The CMD256 die is a broadband MMIC GaAs

x2 passive frequency multiplier. When driven

by a +15 dBm signal, the multiplier provides 15

dB conversion loss at an output frequency of 34

GHz.

The Fo isolation is 38 dBc.

The

CMD256

is

a

50

ohm

matched

design

eliminating the need for RF port matching.

► Low conversion loss

► Excellent Fo isolation

► Broadband performance

► No bias required

► Small die size
