Rockwell
Rockwell were developing a 2 chip DECT solution similar to their PHS offering, but are
reported by one of our DECTweb members to have since discontinued this in favour of
development of spread spectrum devices instead. Certainly DECT seems to have
disappeared from the wireless part of their company website.
Siemens Semiconductors
Following the recent change of name, march 1999, Siemens Semiconductors is now

Texas Instruments
Texas Instruments supply a set of devices designed to facilitate a
DECT RF solution:
TRF1012
transceiver - double down conversion superhet receiver, with an image
reject mixer (to eliminate the need for expensive filters). It has an integrated
demodulator, with outputs compatible with most baseband chips. The transmit chain
comprises a single sideband up converter (again eliminating expensive
filters) and provides 0dBm output. RF VCO's and LNA functions are included on
chip, although an external LNA can be used in applications requiring higher
sensitivity. Power down mode. 3V operation
TRF2052
synthesiser - a dual-channel low power phase locked loop designed to
operate alongside the 1012. 3-wire programming. A speed-up mode allows fast
lock times for non-blindslot hopping using the RF and IF VCOs of the TRF1012. Power
down mode. 3V operation
TRF8012 RF PA
- sampling 1Q99, based on RFMOS technology, this PA provides a selectable output of
+26 or +27.5 dBm. 3.6V supply.
The TI solution is designed for a range of applications - WLL, PABX - providing
fast hopping (no blind slots)and the global enhanced DECT frequency band - up to 1930 MHz.
Evaluation boards are available from TI, to TBR6, including documentation and
software.

VWS23030 IC
Vega 1, VWS23101, a high-integration processor for use in handsets/domestic basestations. Functionality includes burst mode logic, transcoder, codec, memory,32 bit ARM (with echo cancellation software)
Vega VMax, VWS23112, high integration for use in wireless local loop and WPABX applications. Functionality as the Vega 1, plus high speed data support (RS codec and FEC for LU7 64 kb/s on all channels), versatile interfaces (2 Mb/s PCM/ADPCM, 1.5 Mb/s PCM/ADPCM, IOM-2 TE, IOM-2 NT modes) and other features.
The new Vega+ product announced November 1998 combines the existing Vega technology with on-chip memory, additional signal processing capabilities and lower-pin-count packages. Using 0.25um silicon it is targeted at cost sensitive handset and basestation products and allows the implementation of many features that previously required off-chip components. The device has a programmable master clock speed, to enable performance / power consumption trade-offs.
