Raltron VCXO Targets Ultra Low Phase Noise Reference Clocks for High Performance Timing and RF Systems

Miami, FL – April 23, 2026 – Raltron, a global leader in high‑performance frequency control components, wireless antenna products, and high-quality audio components, announces the VC8620D-D3-20-100.000-4-5, a low phase noise 100 MHz sine-wave voltage controlled crystal oscillator (VCXO) optimized for satellite payloads, ground stations, test & measurement, and high-performance synthesizer reference clock architectures. Delivering both excellent close-in phase noise and long-term stability, the new VCXO is ideal for LO, PLL, and clock distribution schemes where every decibel of noise and jitter directly impacts link budgets and system resolution.

The VC8620D-D3-20-100.000-4-5 provides a nominal 100.000 MHz output to drive mixers, PLL ICs, and clock buffers without additional amplification. With low spurious levels of -80 dBc and no sub-harmonics, designers can maintain clean spectral masks in dense RF environments typical of satellite transponders and multi-band synthesizers.

Engineered as a precision reference, the VCXO is well-suited for long-life satellite ground infrastructure and mission-critical RF systems, helping maintain narrow channel spacing and stable LO plans over the life of the platform. The low-noise profile of the VC8620D-D3-20-100.000-4-5 supports low-jitter PLLs, high-order modulation schemes, and high dynamic range receivers where phase noise directly impacts EVM and SNR.

Housed in a rugged 14.3 mm × 9.0 mm package with a maximum 5.6 mm height and gold-plated contacts on an FR5 board, the VCXO integrates smoothly onto dense RF boards, synthesizer modules and instrumentation backplanes.

“With this low phase noise 100 MHz VCXO, we set out to give our customers the spectral purity, stability, and long-term reliability they need to unlock the full performance of their RF front ends and PLL architectures” said Sasha Wolloch, President of Raltron.

The VC8620D-D3-20-100.000-4-5 VCXO is available now for use in satellite communications equipment, RF synthesizers, and other phase-noise-critical timing applications. For more information, samples, and ordering details, please contact Raltron at sales@raltron.com or visit www.raltron.com.

Raltron Introduces Ultra‑Stable 10 MHz OCXO with ppb‑Class Stability and Low Phase Noise for Precision RF, Microwave, and Timing Systems

Miami, FL – April 7, 2026 – Raltron, a global leader in high‑performance frequency control components, wireless antenna products, and high-quality audio components, announces the OX6580MK‑HZ‑0.5‑10.000‑12, a 10 MHz oven‑controlled crystal oscillator (OCXO) that provides designers a very stable, low‑noise and fast warm‑up reference for today’s demanding RF, microwave, and test‑and‑measurement equipment.

Manufactured in Raltron’s Miami facility, the OX6580MK‑HZ‑0.5‑10.000‑12 maintains an extremely stable frequency over temperature, providing ±5 ppb frequency stability from −20 °C to +70 °C. This enables equipment to stay on‑channel across changing environmental conditions, while design engineers can rely on tight initial accuracy and carefully controlled long‑term drift, to reduce recalibration needs and help maintain consistent performance over the life of the product.

The OX6580MK‑HZ‑0.5‑10.000‑12 is engineered for very low phase noise close to the carrier, making it well suited as the master 10 MHz reference for PLL‑ and DDS‑based synthesizers, local oscillators (LO) chains, and precision measurement instruments.

The OX6580MK‑HZ‑0.5‑10.000‑12 is ideal for RF, Infrastructure, and Test Equipment including:

  • Wireless infrastructure such as 4G/5G base stations and microwave backhaul, where tight stability and low noise help improve data throughput and signal quality.
  • RF and microwave synthesizers used in communication, radar, and satellite systems, which need a clean 10 MHz “heartbeat” to generate low‑noise local oscillators.
  • Timing modules and frequency standards, including disciplined oscillators and timing cards that must hold accuracy over long periods and during network or GNSS outages.
  • Test and measurement instruments like spectrum analyzers, signal generators, and frequency counters, which depend on a precise 10 MHz time base for accurate readings and low residual phase noise.

“With its combination of tight temperature stability, excellent noise performance, and rugged environmental qualifications, this OCXO gives design teams a straightforward way to raise overall system performance,” said Sasha Wolloch, President of Raltron. “They get a high‑end 10 MHz reference without having to redesign their architecture or add complex supporting circuitry.”

Raltron Introduces Ultra‑Low Phase Noise 100 MHz OCXO for High‑Performance RF and Microwave Systems

Miami, FL – March 26, 2026 – Raltron Electronics, a leading global manufacturer of frequency management components, audio components, and antenna solutions, announces the release of the OX6580MK‑D3‑20‑100.000‑12, a 100 MHz oven controlled crystal oscillator (OCXO) optimized for applications that demand exceptional close‑in phase noise and long‑term frequency stability. Manufactured in Raltron’s Miami facility, the new OCXO provides an ultra‑clean 100 MHz reference that enables higher dynamic range, lower jitter, and improved spectral purity in state‑of‑the‑art communications, radar, navigation, and test & measurement systems.

The OX6580MK is designed for ultra‑low phase noise, delivering both excellent close‑in and far‑out performance to keep phase‑noise skirts and reciprocal mixing products well below critical signal levels. In high‑resolution test and measurement equipment, its low internal noise floor enables more accurate characterization of phase noise, jitter, and spectral purity of the device under test.

Target Applications

The 100 MHz OX6580MK OCXO is ideal as a low‑noise reference in:

  • Microwave and RF communications equipment, for improved link budgets and tighter constellation performance in complex modulation schemes.
  • Radar and electronic warfare systems, where low phase noise translates into better range resolution, Doppler accuracy, and clutter suppression.
  • Test and measurement instruments, including signal generators, spectrum and phase‑noise analyzers, and frequency counters requiring ultra‑low reference noise floors.
  • Navigation, GNSS, and timing subsystems that rely on stable, low‑noise references for holdover and precise synchronization.

“With phase noise levels down to −178 dBc/Hz at 100 kHz offset and tight ppb‑class stability, this 100 MHz reference ensures that designers are no longer limited by the oscillator in their most demanding RF, radar, and instrumentation architectures,” said Sasha Wolloch, President of Raltron.
