QHx220

Software GUI

A software interface is provided to facilitate the control

of the evaluation board. The GUI can be used to

control of the internal gain stages and DACs via a SPI

bus interface. These two control signals are also

referenced to as “I” (in phase”) and “Q” (quadrature

phase) control in the user interface. The QHx220

controller software is an application that uses the USB

port of a PC to emulate the SPI bus communications to

device. The initial user interface will look like the

following:

The left tab within the window allows the user to

directly set or sweep the I and Q values that control

the QHx220. The right tab allows the user to control

the Phase & Amplitude (which is simply a

mathematical conversion of the I and Q values).

Similarly to the I and Q panel, the Phase & Amplitude

panel can be used to set or sweep the amplitude and

phase of the QHx220 and is often a more intuitive

approach to performing the optimization. In both cases

a small window appears in the bottom right corner to

illustrate the alternate I & Q or Phase and Amplitude

representation.

About Q:ACTIVE

Q:ACTIVE Technology is behind Intersil’s ability to

insert its ICs inside radios, automotive infotainment

systems, satellite broadcast equipment, and various

consumer electronic devices such as GPS units, cell

phones, and portable gaming systems. By doing so,

Intersil achieves the ability to reduce electromagnetic

interference by as much as 30dB. This breakthrough in

radio sensitivity allows for several signals to run

simultaneously and enables new technologies such as

mobile TV on hand held games, cell phones, and in

automotive systems.
