1.3 RF Description

The RF transceiver exceeds the specifications and requirements of the Bluetooth 5.0 PHY specification.

The main features of the RF transceiver are the following:

•

Ultra-low-power: The peak current in receive mode is 3.0 mA and in transmit mode is 5.2mA at

0.4dBm and 3.0V in DCDC Step-Down Configuration at room temperature.

Excellent RF performance: including -94dBm sensitivity for 1Mbps operation with 37 byte

payload and a programmable output power range from -34dBm to +6.1dBm

Low-voltage: Operation from 3.6V down to 1.05V

•

Very high degree of integration: small footprint with few external components

Figure 4: RF Transceiver Block Diagram

The RF transceiver is based on a low-IF architecture and comprises the following building blocks:

•

Single-ended 50 Ohm RF port with on-chip harmonic filter

High gain, low power, LNA and mixer

Power Amplifier with programmable output power range

Low-IF receiver with 5th order channel filter and ADC converter

Fully integrated frequency synthesis with fast settling time and digital modulation

48MHz XTAL reference with finely trimmable internal loading capacitor
