STB4395 Datasheet CT2 RECEIVER/TRANSMITTER

Manufacturer: STMicroelectronics

General Description

The STB4395(A) is a fully integrated receivertransmitter designed for CT2 applications, and incorporates all the VCO’s, synthesizers, PLLs, and channel select logic, to make a fully functional ”single chip” radio.

The receiver is of the double superhet architecture and operates from an aerial input (via a SAW filter) to bitstream output to CT2 format, whilst the transmitter operates from I/Q inputs to +13dBm at the final frequency.

A single (external) frequency reference is all that is required to give full coverage over the range of 800 to 1000MHz.The on-off slope of the Transmit PAis governed internally to give the required switch-on ramp, whilst the output can be swiched from low to high power by means of an external digital control signal.
