Active Frequency Multipliers

Passive Frequency Multipliers


	Active Frequency Multipliers

2x to 8x multiplication

Typical output power: +17 dBm for 18-48 GHz and +7 dBm for 48-110 GHz

K-connectors or waveguide flanges

Balanced configuration

Input power: +10 to +20 dBm

DC power +7 to +15 V or +5 V regulated

300 mA typical


	Active Frequency Multipliers provide larger output power than the passive multipliers described on page 9 and 10 of the Spacek Labs catalog.


	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.

	MM-Wave Frequency Multipliers


	Varistor Multipliers


	The standard multipliers described below utilize variable resistance Schottky barrier diodes as the nonlinear element. All are of balanced configuration to suppress undesired harmonics, unconditionally stable for any input/output VSWR and they cover complete waveguide bandwidth (except at W-Band).
