The DAD-1840 consists of two high performance doublers with a broadband amplifier to provide a quadrupled output with excellent harmonic suppressions across a broad bandwidth. The DAD-1840 simultaneously rejects the first, second, and third harmonics, allowing filtering requirements to be relaxed. It is an excellent alternative to expensive millimeter wave synthesizers for lab use.
