2.1 Transmitter
BGT24LTR11 has a single-ended transmitter output TX (pin 11) with a typical output power of 6 dBm. The
transmitter's output may be enabled and disabled by applying appropriate voltages to TX_ON (pin 5) as shown
in Table 1.
Disabling the TX output will not save power, as the output will be switched to an internal load while the rest of
the chip is still running. This is necessary in case one wants to implement a software-controlled oscillator, as
explained in section 4.
