Introduction

The SR1020 is a digitally programmable UWB wireless transceiver. It transmits in the license-free UWB spectrum from 6.0 - 9.3 GHz by using short impulses that enable highly robust and energy efficient communications. The transceiver allows for the dynamic shaping of its output spectrum to comply with international UWB emission limits or tailor its emissions to a wide range of spectral masks. The circuits are aggressively duty cycled to enable ultra low power operation. The ASIC is composed of an impulse radio with an RF transmitter and receiver, power management unit, sleep counter and digital / baseband hardware. The ASIC communicates over an SPI interface to an MCU running the link layer. The SR1020 can achieve ultra-low power consumption within a wide range of data rates making it a highly versatile solution. It is an excellent solution for wireless applications that benefit from high degrees of energy efficiency, short latency, versatile operation or robust communications.
