Features

The BK69 is a Synthesized UHF Transceiver for use in wireless data transmission applications and is designed to comply to the European Standards EN300-220-3 and EN301-489-3 in accordance with the CEPT-ERC-REC 70-03 recommendation ( Annex 1 - Non Specific Short Range Devices ).

Together with precision and low phase-noise crystal controlled PLL architecture, the transceiver has high reception sensitivity ( -105dBm ) and high RF output power ( 20 mW ). This allows for the employment of poor efficiency antennas ( helical, patch, loop or PCB trace ) so as to remain under the legal 10mW ERP ( Effective Radiated Power ) limit.

The module is designed to be directly interfaced to a microcontroller to control and to monitor the receive and transmit mode and to program ( via a 3-wire serial interface ) the appropriate Rx and Tx frequencies.

In a typical application the also microcontroller also manages the communication protocol ( i.e. the switching between transmit and receive mode ), the preamble, the startbyte and the bit encoding and decoding.
