Frequency Multipliers

Schottky diode Frequency Multipliers are lowest cost and require the least input power (+10 dBm). Output noise is at room temperature (KTBW). The resulting current waveforms, however, have a high duty cycle (ie, square wave=50%) and therefore, higher multiplier harmonics above the fifth decay quickly.

Step-recovery diodes have impulsive waveforms with comb-like output spectrums. The Frequency Multiplier input circuit is more complex requiring a compromise between bandwidth and efficient coupling to the low diode series resistance. The required input power is a function of the SRD capacitance and quickly rises with frequency (+20 dBm typical at 1 GHz).

The hyper abrupt varactor diode (indistinguishable at high frequencies from the SRD) yields the higher output powers and efficiency, provided that unwanted sidebands are reactively terminated. Narda-MITEQ has successfully made efficient frequency doublers and prescalers (halfers) at 10 and 20 GHz.

Narda-MITEQ maintains dedicated engineering resources to modify our standard designs in support of custom-generated specifications that are typically required in stringent system applications. These critical requirements often require high spectral purity. Narda-MITEQ can obtain high levels of fundamental and spurious signal suppression as required in many frequency source applications by employing special
filter technologies.

In addition to custom-filter designs, Narda-MITEQ also has advanced amplifier technologies which, when combined with balanced multiplier designs, offer high performance active multipliers, especially in the areas of shaped frequency response and desired output levels.
