BKx BK Series Module Dimensions 33 mm x 5 mm The BKxx series of modules offers a wide choice of frequency band selection: 69 MHz, 35 or 434 MHz, 868 or 95 MHz. The modules are NBFM (Narrow Band Frequency Modulation).5 or 5 khz channel separation programmable and are based on the Analog Devices AD70N high performance Narrow-Band Transceiver IC. The BKxx complies with the most important Narrow-Band Standards: ETSI EN300 0 ( v.3.), FCC Part 5 Part 95, ARIB STD-T67. A narrow channel separation together with a high receiver selectivity allows to obtain an exceptional RF link budget figure of more then 30 db for a stable and long range communication. A wideband, high efficiency UHF power transistor is employed to increase the TX output power to over 00 (on the Frequency Bands were it is allowed) together with a low loss low pass filter and antenna T/R Switch. A TCXO with,5 ppm stability over the entire temperature range assures long term reliability to the wireless radio link. Applications: - Automatic Meter Reading on 69MHz - 00 - Tracing & Assett Tracking - Social Alarms - Remote Control BK Layout TABLE PERFORMANCE DATA BKx RECEIVER SECTION Frequency 80 to 650 MHz / 84 to 96 MHz¹ Modulation FSK GFSK RCFSK 3FSK 4FSK Receiver sensitivity - dbm KBPS with FSK Modulation Channel Selectivity 9 KHz 3,5 KHz 8,5 KHz Data rate Default kbps Max 8 kbps Supply current Average : 0 ma Power Down : 00 na Supply Voltage 3.3 VDC ± 5% Operating temperature range -40 C 85 C Storage temperature range +65 C 5 C TABLE PERFORMANCE DATA BKx TRANSMITTER SECTION Frequency 80 to 650 MHz / 84 to 96 MHz¹ Modulation FSK GFSK RCFSK 3FSK 4FSK Output RF power Programmable from +0dBm Typical Max +0 dbm +3 dbm to +3 dbm Data rate Default Max kbps 8 kbps Supply current Active : 5 ma (00mA) Power Down : 00 na Supply Voltage 3 3.6 VDC ± 5% Operating temperature range -40 C 85 C Storage temperature range +65 C 5 C Pin Out

PLEASE CONTACT THE FACTORY FOR SAMPLES AND AVAILABILITY OF NON STANDARD VERSIONS. PLL Synthesized Data rate to 64 KB -06dbm Rx Sensitivity The BK67F5 is a synthesized UHF transceiver for use in wireless data transmission applications. The transceiver operates on the 433.05 434.79 MHz ISM band and it is designed to comply to the European Standards EN 300-0-3 and EN 30-489-3, in accordance with the CEPT- ERC-REC 70-03 recommendation (Annex Non Specific Short Range Devices ). Together with a precision and low phase-noise crystal controlled PLL architecture, the transceiver has high reception sensitivity (-05 dbm) and high RF output power ( 0 ). High RF output power allows to employ poor efficiency antennas ( helical, patch, loop or a trace on a PCB) to remain under legal 0 ERP ( Effective Radiated Power ) limit. The BK67F5 is designed to be directly interfaced to a microcontroller (MCU) to control and to monitor the receive and transmit mode and to program (through a 3 wires serial interface ) the appropriate Rx and Tx frequencies. In a typical application the MCU manages also the communication protocol i.e. the switching between transmit and receive mode, the preamble, the start byte, the bit encoding and decoding and other important operations LPD DATA TRANSCEIVER OPZ.
