The PT11MH High-Power
915 MHz Band Transceiver

The PT11MH is the newest in our line of versatile microcontrolled transceivers. It is a compact, ready-to-use, FCC-certified Frequency Hopping Spread Spectrum transceiver that operates in the license-free 902 - 928 MHz band. It is ideal for OEM applications that require a wireless data connection, and it can also be integrated into existing systems. This versatile module will simplify the task of sending and receiving data, using the latest RFIC technology and a customizable TI MSP430 microcontroller. The PT11MH can work in systems with or without an external processor. When there is no host for the system or for specialized applications, Pegasus can customize the microcontroller firmware to meet your needs. Low operating power requirements and very low power consumption in shut down mode make this the ideal module for applications where long battery life is important. The PT11MH features small size, customizability, and low power consumption with the advantages of high power output. This module is in production and is already being used in several different applications.
