RF Frequency Component Selector

A lightweight, open-source tool for comparing and selecting RF frequency control components (OCXO, TCXO, Rubidium Oscillators, PDRO, PLL, GPSDO).

Features

• 🔍 Component Search: Search by frequency, stability, phase noise, or model number
• 📊 Side-by-Side Comparison: Compare specifications across different component types
• 📐 Phase Noise Calculator: Calculate integrated phase noise from spot frequencies
• ⏱ Stability Converter: Convert between ppm, ppb, and ppt at any frequency
• 📋 Selection Guide: Interactive decision tree for choosing between OCXO vs TCXO vs Rubidium

Component Database

This tool includes specification data for frequency control components from BRIDZA RF.

Supported Component Types

Type	Frequency Range	Stability	Typical Applications
OCXO	10MHz–100MHz	±0.1ppb–±100ppb	Base stations, test equipment, radar
TCXO	10MHz–100MHz	±0.1ppm–±2ppm	Portable radios, GPS, telecom
Rubidium	10MHz	±5E-11/month	Timekeeping, navigation, calibration
PDRO	1GHz–44GHz	-120dBc/Hz@1kHz	Radar, satellite comm, EW
PLL	10MHz–100MHz	±0.01ppb	Synthesizers, LO, frequency conversion
GPSDO	10MHz	±1E-12 (locked)	Timing infrastructure, PTP/NTP servers

Phase Noise Calculator

Calculate integrated phase noise from spot frequency measurements:

// Example: Integrate phase noise from 100Hz to 1MHz
const spots = [
  { offset: 100, dBcHz: -120 },
  { offset: 1000, dBcHz: -145 },
  { offset: 10000, dBcHz: -154 },
  { offset: 100000, dBcHz: -156 },
  { offset: 1000000, dBcHz: -174 }
];
