Analog Domain
This single-chip radio transceiver provides a complete radio transceiver interface
between the antenna and the microcontroller. It comprises the analog radio transceiver
and the digital demodulation including time and frequency synchronization, and data
buffering. The number of external components is minimized such that only an antenna,
a crystal and four decoupling capacitors are required. The bidirectional differential
antenna pins are used for transmission and reception, so that no external antenna
switch is needed.
The AT86RF230 block diagram is shown in Figure 3-1.
The received RF signal at pins RFN and RFP is differentially fed through the low-noise
amplifier (LNA) to the RF filter (PPF) to generate a complex signal. This signal is
converted down by mixers to an intermediate frequency and fed to the integrated
channel filter (SSBF). The limiting amplifier provides sufficient gain to drive the
succeeding analog-to-digital converter (ADC) and generates a digital RSSI signal with
3 dB granularity. The ADC output signal is sampled by the digital base band receiver
(RX BBP).
The transmit modulation scheme is offset-QPSK (O-QPSK) with half-sine pulse shaping
and 32-length block coding (spreading) according to [1]. The modulation signal is
generated in the digital transmitter (TX BBP) and applied to the fractional-N frequency
synthesis (PLL) generating a coherent phase modulation required for demodulation of
O-QPSK signals. The frequency-modulated RF signal is fed to the power amplifier (PA).
An internal 128 byte RAM for RX and TX (Frame Buffer) buffers the data to be
transmitted or the received data. Two on chip low dropout (LDO) voltage regulators
provide the internal analog and digital 1.8V supply.
