PBL40215

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.

PBL40215 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 of PBL40215 comprises of a signal gate and a pre-power amplifier. Data transmission is achieved by direct open loop modulation of the Tx VCO.
