R92.00

Features

CE Certified by independent Notified Body
Verified to comply with harmonised radio standard ETSI EN 300 220-3 by accredited Test Laboratory
Verified to comply with harmonised EMC standard ETSI EN 301 489-3 by accredited Test Laboratory
Data rates up to 160kbps
Usable range up to 300m
Fully screened

Available for operation at 433.92 MHz in Europe/South Africa, the module combines full screening with extensive internal filtering to ensure EMC compliance by minimising spurious radiations and susceptibilities. The TX2 and RX2 modules will suit one-to-one and multi-node wireless links in applications including car and building security, EPOS and inventory tracking, remote industrial process monitoring and computer networking. Because of their small size and low power requirements, they are ideal for use in portable, battery-powered applications such as hand-held terminals.

Functional description

The TX2 transmitter module is a two stage, SAW controlled FM transmitter operating between 2 and 6 V, transmit frequency 433.92MHz. The unit is type-approved to EN 300 220-3 for European use and will deliver +9 dBm from a 5V supply at 12mA. The module measures 12 x 32 x 3.8 mm.

The RX2 module is a double conversion FM superhet receiver capable of handling date rates of upto 160kbit/s. The SIL style RX2 receiver measures 48 x 17.5 x 4.5 mm. It will operate from a supply of 3-6V and draws just 14mA when receiving. A fast-acting carrier detect and a power-up enable time of less than 1ms. This allows effective duty cycle power saving and a -107dBm sensitivity. This, combined with a SAW front-end filter results in an excellent RF performance and EMC conformance.
