- Receiver
The receiving signal from the antenna is input to the RFIC (IC502) after being passed through the
Antenna Switch (IC506) and amplified at LNA (Low Noise Amp). The RFIC (IC502) incorporates the LNA
(Low Noise Amp), the Mixer for Frequency Converter and the Synthesizer generating the Receiving
Local Signal. At the RFIC (IC502), the input signal is separated into the baseband signals of the In-
Phase(RxI) and Quadrature (RxQ) to output.
The baseband signal is input to the CPU&MAC/BBIC(IC601) and, after A/D conversion, the data are
regenerated.
- Transmitter
The Data Frame (Data Packet) generated at the built-in MAC Part by the CPU&MAC/BBIC (IC601) is
converted to the In-Phase (TxI) and the Quadrature (TxQ) and input to the RFIC (IC502).
At the RFIC (IC502), it is converted to the RF Signal of the transmitting frequency band.
After processing including impedance conversion, level adjustment and control of the unnecessary
frequency component, it is sent from the antenna through the Antenna Switch (IC506).
The RF Signal from the Power Amp (IC505) is fed back to the RFIC (IC502) after level detection. The gain
is adjusted in the RFIC (IC502) for a constant transmitter output level.
