Published: 13 August 2014 - Marianne Evans
SAW Filters are widely used in commercial and military radio communication systems, consumer electronics and industrial applications given their superior performance, small size and low cost. To service this demand Aspen Electronics have brought Nanjing Electronic Devices Institute (NEDI) to the UK and European markets.
NEDI have developed more than one thousand different types of SAW resonators and filters with excellent quality and high reliability. The ND series of Saw Filters, for example, are available in both leaded and surface mount configurations in packages such as TO39, F11 DCC6 and QCC8.
The wide range offers centre frequencies from 30MHz to 2.4GHz; Bandwidths of 0.02 to 60%; Insertion loss of between 2 and 35dB’s; Amplitude ripple of 0.2 to 2.0db with corresponding Group delay ripple of 10 to 500ns.
The devices find applications in signal processing, frequency selection and control in audio-video, communication and remote control systems found in the Mobile Communication, Satellite Communication, Base Station, Security Systems and Data Transmission industries to name just a few.
In addition to a standard product portfolio NEDI are also able to accommodate custom designs to meet customers’ specific needs. The company also has an aggressive programme of developing new products for existing and emerging markets. To that end Nanjing Electronic Devices Institute has excellent R&D facilities, highly skilled workers and cost-effective material sourcing and can be considered to be a leading supplier of SAW components in China.
Production is carried out to the ISO 9001:2000 Quality System, for which the company has full qualification certification.
