Introduction

WirelessUSB NL enables a Gaussian frequency-shift keying (GFSK) radio by using a differentiated single-mixer, closed-loop modulation design that optimizes power efficiency and interference immunity. Closed-loop modulation effectively eliminates the problem of frequency drift, which enables WirelessUSB NL to transmit up to 255-byte payloads without repeatedly having to pay power penalties for relocking the phase-locked loop (PLL) as in open-loop designs.
