TUMA1: Ultra-Low Jitter Reference Oscillator Provides Foundation for High-end Communication Systems

Presentation Abstract
Next-generation communication and radar systems require wide bandwidth signals to support high data rates and enhanced resolution.  Low phase noise systems are critical in high-QAM rate and OFDM signals to minimize bit error rate (BER) and to maintain signal integrity.  Digitally controlled reference oscillators provide excellent integrated jitter performance for high-end systems with programming flexibility to address different system configurations.  The solution highlights a temperature-controlled reference oscillator (TCXO) for a PLL/VCO integrated into a microwave up/down converter.  The presentation highlights the composite Error Vector Magnitude (EVM%) performance upconverting a 5GNR signal up to 26 GHz with various sub-carrier spacings.
