The Low-Noise Amplifier (LNA) operates with TR-Combined mode with LPA for single port
application. It removes the need for an external TX/RX switch.
The ADC is used to sample the input analog
signal and convert it into a digital signal for
demodulator analysis. A channel filter has been
integrated into the receiver channel before the
ADC, which is used to reduce the external
component count and increase the anti-interference
capability.
The image rejection filter is used to reject
the image frequency for low-Intermediate Frequency
(IF) architecture and to reduce external Band Pass
Filter (BPF) component for a super heterodyne
architecture.
Received Signal Strength Indicator (RSSI)
signal feedback to the processor is used to
control the RF output power to make a good
trade-off for effective distance and current
consumption.
