Preliminary
RF Transceiver circuit for the Digital
Enhanced Cordless Telecommunications
(DECT) system
PBL 402 15
Description.
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.
