STLC2150

Transmitter

All output power specifications are given at the antenna port, with a bandpass filter and matching network in

between the port and the IC. The loss between antenna port and IC output is approximately 2 dB

PLL

The centre frequency of the radio transmit or receive channel is controlled by a PLL. The selected radio channel

centre frequency is given by:

Fc = 2.400GHz + n*1 MHz,

where "n" is a 7-bit channel control word, ranging from 2 to 97
