Device Overview

General Description

The AQA-2156 is an amplified frequency multiplier that quadruples the 5.25 – 14 GHz input frequency, producing an amplified 21 - 56 GHz quadrupled output frequency. This multiplier is designed to provide +20 dBm 4F output power with +0 dBm input power and offers superior harmonic suppressions. It can provide sufficient LO drive for Marki S-, H-, and L- diode mixers.

[1][2] Current consumption taken under NO RF input power. Current draw will increase with increased input power. Optimal Performance is at approximately +3.5V / -5.0V.

[3] Optimal suppression levels at -10 - 0 dBm input power.

[4][5][6][7] Suppression is defined as the harmonic power relative to the 4F quadrupled output power.
