DECT transceiver sets Korean standard

RF device is one of the first DECT transceivers that operates in 1786 to 1803MHz frequency range defined for KDECT.

SiTel Semiconductor has confirmed its support for the Korean Digital Enhanced Cordless Telecommunications (KDECT) standard.

The company's existing LMX4169 RF chip is one of the first DECT transceivers that operates in 1786 to 1803MHz frequency range defined for KDECT.

This flexible single-chip front-end ensured Acro Telecom could deliver its first customer's KDECT phone within a very short time to market.

SiTel has also confirmed its intention to expand its Cordless ROM Kit (CRK) range to support the new South Korean frequency range.

"SiTel is committed to the Korean digital cordless market and customers", says HK Teoh, Sales and Marketing Manager of SiTel Semiconductor Asia Pacific.

"By offering best-in-class chips and development support, we aim to become the key technology provider for the KDECT market".

"And through the use of a conventional CMOS process for our RF ICs, we can guarantee small, cost-effective solutions and an extremely reliable supply".

The LMX4169 is a single-chip CMOS RF transceiver with a high sensitivity (-96dBm), allowing long-range communications while maintaining crisp voice quality.

Covering all existing DECT frequencies, it can be simply programmed to operate at the lower KDECT frequencies.

Fully compatible with Sitel's range of advanced basebands, the LMX4169 ensures complete solutions for KDECT are available for full production.

Based on SiTel's proven technology and developed by Korean-based Acro Telecom, the Ann KDECT-enabled digital cordless phone is one of the leading platforms to be launched in this market.

"The early availability and modularity of SiTel chipsets supporting Korea DECT made developing the Ann phone very easy", says Kim Kyoung Hyun, President of Acro.

"The short development time also helped us deliver the handsets in an extremely competitive time to market".

With the CRK handset, manufacturers benefit from a modular platform that supports seamless interchangeability between KDECT, DECT, DECT 6.0 and 2.4G.

This versatility helps produce cost-effective solutions by allowing manufacturers to quickly and easily adapt existing products to different regional market requirements.

Consequently, the CRK provides a low-risk, low-investment path with fast time to market.

In production since 2005, the CRK has been extensively tested and proven in the field.

The CRK contains a baseband controller embedded with DECT software for KDECT, DECT, DECT 6.0 and 2.4G, RF and baseband schematics, manufacturing documentation, module samples and the printed-circuit-board (PCB) layout.

It also allows customers to support a complete range of products from entry-level to high-end through the choice of external microcontrollers for the man-machine interface.
