Full Band Active Multipliers

Active Frequency Multipliers provide larger output power than Spacek Labs passive multipliers. Achievable output power is typically 17 dBm up to 48 GHz and 7 dBm for 50 to 110 GHz output frequency range, more for narrowband models. Standard multipliers are of balanced or doubly-balanced configuration to provide at least 15 dB undesired harmonics suppression even without using output filters. This is important for multipliers with octave bandwidth where filters cannot be used because the desired and undesired harmonics overlap. However, filters are used for narrowband multipliers giving at least 50 dB improved signal purity. In addition to the standard multipliers described below, custom designed units are available with large selection of input/output powers, frequencies and multiplication ratios.
