TM2502/3/4

5.8GHz FSK/GFSK Transceiver IC with 4Mbps with 5dBm/18dBm/23dBm ( option)

5.8GHz FSK/GFSK Transceiver IC with 4Mbps with high power out max. The IC includes Power amplifier Low noise amplifier, RF switch and a 4Mbps RF transceiver. It bottom side has Thermal GND. It pin is stamp and leadless type pin pad for get easier soldering. The IC is a highly integrated GFSK RFM operating in the world wide ISM frequency band at 5.15~5.85 MHz Burst mode transmission and up to 4Mbps air data rate make them suitable for applications requiring ultra low power consumption. The embedded packet processing engines enable their full operation with a very simple MCU as a radio system. Auto re-transmission and auto acknowledge give reliable link without any MCU interference.

The IC operates in TDD mode, either as a transmitter or as a receiver. The RF channel frequency determines the center of the channel used by TM2502. The frequency is set by the RF_CH register in register bank 0 according to the following formula: F0=5150+RF_CH (MHz). The resolution of the RF channel frequency is 1MHz. A transmitter and a receiver must be programmed with the same RF channel frequency to be able to communicate with each other. The output power of TM2502 is set by the RF_PWR bits in the RF_SETUP register.

Demodulation is done with embedded data slicer and bit recovery logic. The air data rate can be programmed to 4Mbps by RF_DR register. A transmitter and a receiver must be programmed with the same setting. In the following chapters, all registers are in register bank 0 except with explicit claim.

5.8GHz FSK/GFSK Transceiver IC with 4Mbps with 23+ dBm. The IC includes Power amplifier Low noise amplifier, RF switch and a 4Mbps RF transceiver. It bottom side has Thermal GND. It pin is stamp and leadless type pin pad for get easier soldering.
