UHF Multi-channel Transceiver for Industrial Remote Control and Telemetry Applications

Saelig has introduced a half-duplex UHF radio module suitable for industrial remote control and telemetry applications operating in the 434 MHz ISM band. The new, STD-302Z 434 MHz Narrow Band Multi-Channel Transceiver is designed with SAW filter and narrow-band filtering techniques to provide reliable data communication in industrial situations where interference rejection and practical distance range operation are required.

Offering 10 mW of RF power from its PLL-synthesized transmitter with programmable RF channels, the STD-302Z's double super-heterodyne receiver sensitivity is specified down to -119 dBm. It has an operating temperature of -20 to +60 Degrees C and provides excellent vibration and shock resistance for products that are mobile or subject to movement. Suited to feedback systems, industrial remote controls and telemetry, the STD-302Z complies with the European Category 1 (EN300 220).

An RSSI (Received Signal Strength Indication) output is also provided which corresponds to the received signal level. This voltage can be used for functions such as carrier sense, channel auto select, and electric field strength monitoring. When the STD-302Z is powered on, data transmission and reception is possible 40 ms after the frequency setting data is sent to the PLL.

Compact (1.2" x 1.97" x 0.36") and lightweight (1oz), it's operating voltage is +3.0 to 5.5V, with internal circuitry operating at a regulated 2.8V. The TB-STD302 evaluation board is also available, which simplifies trying out the STD-302Z module's performance, such as range and signal transmission integrity. Designed with a maximum RF output power of 10 mW, it is ideal for the remote control of industrial equipment or for industrial measurement systems.

The STD-302Z is made by Circuit Design, a leading Japanese low power radio product design and manufacturing company.
