TCXO for Sync, GNSS & Satcom Timing: A Practical Board-Level Design GuideHow to think about phase noise, jitter, stability and packages—and how to map them to FVT-9S-LN, FVT-7S-WT and FVT-3S-LJDec 30, 2025·7 min read
TCXO Family for Sync, GNSS & Satcom: Designing the Board-Level Timing LayerWhen we talk about timing in GNSS, satcom and telecom systems, OCXO timing modules and network protocols like SyncE or IEEE 1588 often dominate the conversation. But most real designs are held together by something much more humble: A board-level TC...Dec 23, 2025·8 min read
Building a Timing Stack with SAW Filters, TCXO and OCXOIn many GNSS, satcom and telecom designs, timing is discussed in fragments: RF engineers worry about blocking and noise figure System teams talk about SyncE, IEEE 1588 or GNSSDO performance Hardware engineers fight with PCB layout, jitter and phas...Dec 18, 2025·8 min read
SAW Filter Knowledge Hub: A Practical Learning Path from Fundamentals to PCB RealitySAW (Surface Acoustic Wave) filters sit at a fascinating intersection of physics and real-world RF engineering.They are small, passive components—but in many receivers they decide whether your system stays sensitive, selective, and stable in noisy en...Dec 9, 2025·4 min read
SAW Filter PCB Layout & ESD Design: Turning S-Parameters into Real-World PerformanceMost RF engineers meet surface acoustic wave (SAW) filters for the first time in a datasheet or S-parameter file. On paper, the passband is flat, the stopband is deep, and the group delay looks perfect. Then the first prototype board comes back, and ...Dec 3, 2025·8 min read
