8 Wireless Transceiver
The wireless transceiver comprises a 2.45GHz radio, an O-QPSK modem, a baseband processor, a security
coprocessor and PHY controller. These blocks, with protocol software provided as a library, implement an
IEEE802.15.4 standards-based wireless transceiver that transmits and receives data over the air in the unlicensed
2.4GHz band.

Figure 14: Radio Architecture
The radio comprises a low-IF receive path and a direct up-conversion transmit path, which converge at the TX/RX
switch. This switch includes the necessary matching components such that a 200 Ω differential antenna may be
directly connected without external components. Alternatively, a balun can be used for single ended antennas.
The 16MHz crystal oscillator feeds a divider, which provides the frequency synthesiser with a reference
frequency. The synthesiser contains programmable feedback dividers, phase detector, charge pump and internal
Voltage Controlled Oscillator (VCO). The VCO has no external components, and includes calibration circuitry to
compensate for differences in internal component values due to process and temperature variations. The VCO is
controlled by a Phase Locked Loop (PLL) that has a loop filter comprising 3 external components. A programmable
charge pump is also used to tune the loop characteristic. Finally, quadrature (I and Q) local oscillator signals for the
mixer drives are derived.
The receiver chain starts with the low noise amplifier / mixer combination whose outputs are passed to the polyphase
bandpass filter. This filter provides the channel definition as well as image frequency rejection. The signal is then
passed to two variable gain amplifier blocks. The gain control for these stages and the bandpass filter is derived in
the automatic gain control (AGC) block within the Modem. The signal is conditioned with the anti-alias low pass filter
before being converted to a digital signal with a flash ADC.
In the transmit direction, the digital I and Q streams from the Modem are passed to I and Q quadrature DAC blocks
which are buffered and low-pass filtered, before being applied to the modulator mixers. The summed 2.4 GHz signal
is then passed to the RF Power Amplifier (PA), whose power control can be selected from one of six settings. The
output of the PA drives the antenna via the RX/TX switch.
