21-56 GHz Amplified 4F Multiplier AQA-2156 Copyright © 2020 Marki Microwave, Inc. All Rights Reserved P a g e 1 | R e v . C 1. Device Overview
1.1 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 consists of an input buffer APM-6848 amplifier, MMD-1030H doubler, 2nd APM-6848 buffer amplifier, MMD-1648L doubler, and an output AMM-6702 amplifier. It is capable of providing sufficient LO drive for Marki S-, H-, and L- diode mixers.

2.2 Port Functions
Port Function Description Equivalent Circuit Port 1 Input This pin is for the RF input. It is internally DC-blocked and is matched to 50 ohms from 5.25-14 GHz Port 2 Output This pin is for the RF output. It is internally DC-blocked matched to 50 ohms from 21-56 GHz GND Ground Ground path is provided through the metal housing and outer ground lug. Power Supply Positive bias Positive bias port must be connected to a +3V to +4.5V power supply. Bias Negative bias Gate control for the amplifier must be connected to a -5.0 to -6.0 Volt power supply. Port 2 Power Supply GND Bias Port 1 Power Supply Power Supply Power Supply Bias

3.1 Absolute Maximum Ratings
The Absolute Maximum Ratings indicate limits beyond which damage may occur to the device. If these limits are exceeded, the device may be inoperable or have a reduced lifetime. Absolute Maximum Ratings Parameter Maximum Rating Positive Bias Voltage 4.5 V Positive Bias Current 600 mA Negative Bias Voltage -10 V Negative Bias Current 3 mA RF Input Power +10 dBm ESD (Human Body Model) Class 1A Operating Temperature -40ºC to +50ºC Storage Temperature -65ºC to +150ºC
3.2 Sequencing Requirements
Turn-on Procedure: 1) Apply -5V to Bias port 2) Apply +4V to Power Supply port Turn-off Procedure: 1) Turn off Power Supply port 2) Turn off Bias port
3.3 Heat Sinking
The AQA-2156 module requires sufficient heatsinking (as providing by mounting onto a metal chassis) and/or a fan providing airflow onto the unit. Failure to provide sufficient heatsinking/cooling can result in operating temperatures exceeding the absolute maximum of +50ºC, and will likely cause damage to the unit. The cooling provided by a fan significantly reduces the package temperature and is highly recommended when operating the AQA-2156.
