World’s first pocket DAB receiver

Roke Manor Research and Panasonic System LSI Design Europe have unveiled what they claim is the world’s first hand-held digital audio broadcast receiver.

Roke Manor Research, part of the Siemens group, and Panasonic System LSI Design Europe have unveiled what they claim is the world’s first hand-held digital audio broadcast (DAB) receiver – the Pocket DAB.

The pre-production model measures just 50mm x 76mm x 24 mm. Headphones supply digital quality sound whilst doubling as the receiving antenna. The model also features a full dot matrix display screen that offers up to ten lines of text or graphics and a battery that provides up to five hours of radio listening time per charge.

The heart of the Pocket DAB is Roke Manor Research’s Gold Card II receiver module, which is a complete DAB receiver. It uses the Hitachi HD 155050 radio receiver IC, in combination with Panasonics new MN 66720 DAB baseband IC.

The predecessor to the Gold Card II, the Gold Card, has been used in the Arcam, Radioscape and Roberts digital radio products, as well as providing the core radio design for the Psion Wavefinder.

Paul Smith, Business Unit Director for Radio Devices at Roke Manor Research said, ’The miniaturisation of the DAB receiver will open up the market for digital radio, as it can now be marketed as a small, stylish ’must have’ for the savvy, digital consumer. With Panasonic we are currently engaging partners to take the Pocket DAB to the next stage of commercial development.’
