EPIC represents photonics industry at European Commission group


European Photonic Industry Consortium (EPIC) president Drew Nelson will act as technology representative for the Photonics KET High Level Group. The group aims to foster the industrial deployment of European KETs in order to keep pace with main international competitors, restore growth, create jobs and help address today’s major societal challenges


A new group was launched on 27th February to assist the European Commission in the implementation of the strategy to boost the industrial production of KETs based products in Europe.


The global market in Key Enabling Technologies (KET) is forecast to grow from about €650 billion in 2008 to over one trillion euro in 2015. World leading industries in the fields of automotive, communication, aeronautics, defence, health and energy are all intensive users of KETs.


Representing the European photonics industry, EPIC President Drew Nelson, CEO and President of epitaxial wafer supplier IQE, has been appointed as a member of the new High Level Group as technology representative for the Photonics KET.


working group on “Promotion and Implementation of KETs Policies at National and Regional Level.” “KETs offer a fantastic opportunity for all of Europe, we must explore and embrace its potential. Especially in Photonics, there are many opportunities ahead of us,” he says.


GaAs MMIC I/Q converters for microwave radio revealed by Hittite


The gallium arsenide devices are suited to 38 GHz & 42 GHz applications


Hittite Microwave Corporation has launched several new, highly integrated I/Q upconverter and downconverter products.


They cover the licensed 38 GHz and 42 GHz bands in microwave radios for cellular backhaul radio links.


The HMC6787ALC5A and the HMC6146BLC5A are GaAs MMIC I/Q variable gain upconverters which form a competitive and cost-effective microwave radio transmitter solution which has been designed to meet or exceed all of the performance criteria required for modern high capacity QAM microwave radios.


The HMC6787ALC5A operates from 37 to 40 GHz and provides a small signal conversion gain of 10 dB with 17 dBc of sideband rejection, and 13 dB of gain control.

“I will be a vigorous supporter and promoter of KETs at regional, national, and European level and take every opportunity to help design and implement policies to help the competitiveness of Europe through the rapid deployment of KETs,” states Nelson. “I expect from the KET high level group that it is able to persuade the European Commission through evidence based examples and debate to adapt EU policies throughout each Directorate General that fully support KETs implementation throughout Europe.”


The expert group advises the European Commission on KETs related policy issues, follows up the implementation of the European strategy for KETs adopted by the European Commission on 26th June 2012, and promotes the development of KETs policies by the Member States.

The HMC6146BLC5A operates from 40 to 44 GHz and provides a small signal conversion gain of 12 dB with 25 dBc of sideband rejection, and 17 dB of gain control.


Both devices utilise a RF variable gain amplifier preceded by an I/Q mixer where the LO is driven by a x2 multiplier. IF1 and IF2 mixer inputs are provided and an external 90 degree hybrid is needed to select the required sideband.


The I/Q upconverters feature high output IP3 of +27 dBm, 2LO/ RF isolation of 15 dB, and also meet the requirements of VSAT/ Satcom transmitter terminals covering the EHF frequency band.


The HMC6147ALC5A is a GaAs MMIC I/Q downconverter which is ideal for replacing the front end receiver section of 38 GHz and 42 GHz microwave radio designs.
