Description Of The Module
The transceiver module eQ-3 TRX916 contains a true single chip UHF transceiver
designed for very low power wireless applications.
The transceiver module operates within the frequency band 902 MHz to 928 MHz
according to FCC Part 15, Section 15.249. The transmission and receive frequency is set to
916.5 MHz. FSK modulation is done with 19 kHz deviation.
The transceiver module TRX916 provides extensive hardware support for packet handling,
data buffering, burst transmission link quality and wake on radio.
The main operation parameters and the 64-byte transmit/receive FIFOs of the transceiver
module can be controlled via an SPI interface. A system consists of two transceiver
modules integrated in an appropriate terminal equipment, which can be used in each case
as transmitters and/or receivers.
