The RH433-D includes optimal phase, noise blocking and selectivity performance for narrow band and licensed band applications such as FCC Part 90 and 169 MHz wireless M-Bus. The 60 dB adjacent channel selectivity with 12.5 kHz channel spacing ensures robust receive operation in harsh RF conditions, which is particularly important for narrowband operation.

The RH433-D offers exceptional output power of up to +20 dBm with outstanding TX efficiency. The high output power and sensitivity results in an industry leading link budget of 127 dB allowing extended ranges and highly robust communication links.

The RH433-D active mode TX current consumption of 33 mA at +10 dBm and RX current of 15 mA coupled with extremely low standby current and fast wake times ensure extended battery life in the most demanding applications. The RH433-D can achieve up to +27 dBm output power with built in ramping control of a low-cost, external FET.

The devices are compliant with all worldwide regulatory standards: FCC, ETSI and ARIB. All devices are designed to be compliant with 802.15.4g and WMbus smart metering standards.

In addition, compact size and standard RS232 interface will surely help the users develop their wireless applications with ease, cost-effectiveness and reduced time-to-market.
