TCXO (temperature-compensated quartz oscillator)

TCXO provides high stability and frequency control accuracy by compensating for temperature variations. This ensures that signal reception remains stable and reliable, even under extreme temperature conditions. It also reduces frequency drift over time, ensuring long-term stability and eliminating signal degradation.
