The requirement for low cost, light weight, compact and portable laboratory equipment is becoming more commonplace in industry.

High Power Microwave Generator

The microwave amplifier uses GaN on SiC solid-state technology operating in class A/B mode to generate microwave power in excess of 100W CW when used in the internally regulated standalone mode - see Fig.1. In this mode and also [swept] mode, the output power can be varied in 5W increments from 0-100W using pulse width modulation (PWM) techniques with power stability maintained within 5% of the set value.

High Power Microwave Amplifier

The ISYSconnect can also be used as a standard amplifier when used in [external source] mode where a small signal gain of 55-58dB is typical. Using this mode of operation, the amplifier operates without any internal power regulation, allowing the user to have full control of the output power levels.

Advanced Reflection Measurement System

The ISYSconnect has, as standard, an innovative reflected power measurement mode of operation. When used in this [swept] mode, the system has the capability to reduce the reflection measurement error significantly where the input match of the device under test is non-optimal. As an example, for a device with an input match of -12dB connected to the system at a distance in excess of 1m, an improvement of approximately 75% in measurement error is easily achievable thereby reducing the overall uncertainty in the measurement. This mode of operation is particularly useful for applications that are dependent upon the accuracy of reflected signal to identify material properties or relaying test progress and safety.

Superior Cooling

The use of higher operating voltages on the GaN on SiC semiconductors in the ISYSconnect system design helps reduce the drain current and the resultant Joule effect losses.

The system has an amplifier efficiency of ~62% resulting in a low channel temperature rise and also significantly reduced thermal loss requiring reduced thermal management – see Fig 2. The ISYSconnect’s highly efficient design has allowed the implementation of a novel, thermal cooler solution to dissipate heat losses and maintaining the amplifier temperature when operating at full power at below 55 degrees Celsius. The cooling system employed is very compact with superior thermal capacity per unit volume allowing the overall system to be significantly smaller and lighter with an optimised air-flow management system.

The external communication is via a simple parallel data communication interface, as standard.

The major difference between the ISYS245 and the ISYSconnect is the user interface. The ISYSconnect is completely controlled using Emblation's software-based interface – giving users the ability to automate tests and measurements, store data and monitor module behaviour in real time.
