PBL 402 15
RF Transceiver circuit for the Digital
Enhanced Cordless Telecommunications
(DECT) system
Description.
Key features.
The PBL 402 15 is a complete RF transceiver to be used in the Digital Enhanced
Cordless Telecommunications ( DECT ) system. It is designed to interface to various
base-band controllers.
The circuit contains transmit and receive functions that share integrated high stability
VCO´s and a phase locked loop function ( PLL ). All functionality is controlled through a
3-wire bus interface with optional hard wire lines.
The receive section comprises of a low noise image reject down conversion to the
first intermediate frequency, an external channel filter, a second down convertion to a
second intermediate frequency, an integrated channel pass filter, a high gain limiting
amplifier, a received signal strenght indicator with DC compensation loop, a self aligned
frequency discriminator and a preamble based data slicer.
The transmit section comprises of a signal gate and a pre-power amplifier. Data
transmission is achieved by direct open loop modulation of the Tx VCO.
• High Tx output power to +7dBm
• Integrated PLL and high stability
VCO´s
• 3-line serial interface bus
• Minimum 2.7 V supply voltage
• Low current consumption
• Differential Rx input and Tx output
• Flexible interface to various base-
band controllers
• Exellent performance with Ericsson´s
power amplifier PBL403 09
• Low cost
Applications:
• DECT Handset and base station
• Wireless local area network ( WLAN )
• Wireless local loop ( WLL )
