The transmitter design consists of a Bluetooth Chip device connected to an Atmel power amplifier via a matching network and balun. Harmonic filtering, a transmit/receive switch, a ceramic bandpass filter and a SMA connector are also included.
The receiver uses the same antenna, bandpass filter and transmit/receive switch as the transmitter. To improve the sensitivity, the LNA within the Atmel device and the single-ended receiver port of Bluetooth Chip are used.
