RFM98 Long Range Transceiver Module - Support 433M Frequency

Key Features

• Long range modem that provides ultra-long range spread spectrum communication  
• High sensitivity of over -148dBm, optimal for any application requiring range or robustness
• +20 dBm - 100 mW constant RF output vs. V supply
• +14 dBm high-efficiency PA
• Low RX current of 10.3 mA, 200 nA register retention
• Built-in temperature sensor and low battery indicator

Description

The RFM98 transceivers feature the Long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.

Using the patented Long Range modulation technique RFM98 can achieve a sensitivity of over -148dBm using a low-cost crystal and bill of materials. The high sensitivity combined with the integrated +20 dBm power amplifier yields industry leading link budget making it optimal for any application requiring range or robustness.

Long Range also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity, and energy consumption.

These devices also support high performance (G)FSK modes for systems including WMBus, IEEE802.15.4g. The RFM98 delivers exceptional phase noise, selectivity, receiver linearity, and IIP3 for significantly lower current consumption than competing devices.
