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
