We are a UK-based independent manufacturer of oscillators, quartz crystals, filters and frequency-related products. For over forty years, we have been manufacturing and supplying an extensive range of standard and custom frequency control components to customers in more than 70 countries.
As manufacturers, we maintain a dual "from stock or made-to-order" system in order to provide the highest levels of customer service.
Our engineering team is highly experienced in the design and manufacture of electronic filter components and quartz crystals and are happy to give advice and assistance. We nurture design and development partnerships with our customers, who can be assured that our designers and production engineers will be there to assist with major product upgrades and the development of new technology as well as with production and logistic operations.
We have a broad-based policy toward our product range in order to provide maximum flexibility. As such, we have specialist expertise in several product areas, particularly with custom electronic filters, radiation-tolerant oscillators for satellite or high-altitude aerospace applications, and high-reliability oscillators for defence-related applications.
We are committed to providing excellent customer service throughout the entire design, development and manufacturing process, including after-sales support. We are ISO9001(2000) certified, operating a complete quality system with full traceability and regular auditing.

We manufacture a comprehensive range of quartz crystals, and maintain stock of crystals in most popular package styles, specifications and frequencies for fast delivery. If we do not stock the crystal you require, we can provide bespoke crystals to specification in as little as three working days.
This is a brief list of some of the crystals we stock:
• Low-profile, miniature, micro-miniature, ultra-miniature and compact SMD crystals
• Industry standard and miniature cylindrical watch crystals • Ruggedised ceramic packages
• Miniature leaded crystals with tuning fork resonators for Pierce or series oscillators
• Compact size metal can crystals with very close tolerances available for telecom applications
• High-temperature operating range crystals • High shock and vibration survival crystals

We manufacture oscillators in a comprehensive range of packages and output types, including PECL, HCMOS and LVDS. We make oscillators for a diverse range of applications, from low-cost clock oscillators to high-reliability units for aerospace and defence applications. We offer short delivery lead times, even for production quantities with our XpressO configurable oscillator range.
A wide supply voltage range of from 1.0 to 5.0 Volts can be specified for many HCMOS output SMD oscillators.
We also offer low EMI oscillators which use spread-spectrum technology and can reduce EMI by
- 12dB, making these oscillators a true 'EMI solution in one package'.

We offer a wide range of resonators, including ZTTC - SMD resonators with and without capacitors in frequencies ranging from 2.0 MHz to 50.0 MHz. We also offer ZTT resonators, including ceramic resonators with built-in phase-shift capacitors, and ceramic resonators for FM and general applications. These resonators feature stability tolerance of ±0.3%. A comprehensive selection of frequency ranges is available.

We produce a full range of standard filters and also offer custom filters to specification, including ceramic, helical, microwave and monolithic crystal filters.
Ceramic filters include discriminators and traps with frequency range from 4.5 MHz to 6.5 MHz. Ceramic filters are available in 4 element or 6 elements.
Our helical filters feature low insertion loss and impedance and small group/phase delay. They can be manufactured to any Fo between 55 MHz to 1600 MHz with a customer-specified centre frequency and bandwidth with no NRE design charges.
Monolithic Crystal filters are available in a range of standard specifications for general and other applications including UHF mobile radio, cellular and cordless telephone.
We manufacture microwave filters to specification.

We produce TCXOs and VCTCXOs with an extensive range of specification characteristics, output options and package types. All TCXOs are available as RoHS compliant, with most types also being available in non-RoHS compliant versions if specified.
Our TCXO range includes:
• Clipped Sine Wave Output SMD and Through-hole • High Reliability Greenray TXCOs
• Quick Turnaround SMD TXCOs • Square Wave CMOS Output (kHz range) SMD and Through-hole
• Square Wave CMOS Output (MHz range) Low-current, SMD and Through-hole
• Square Wave CMOS Output (V Group) SMD and Through-hole • Square Wave CMOS Output (W Group) SMD and Through-hole
• Square Wave PECL and LVDS Output SMD TCXO

Oven Controlled Crystal Oscillators (OCXO) provide very high degrees of stability in quartz crystal-controlled oscillators. Any variation of output frequency caused by ambient temperature change is minimised by placement of the crystal inside a thermostatically controlled oven.
Our OCXOs are precision designed to provide stabilities from ±0.005ppm over their operating temperature range using SC-Cut crystals or from ±0.02ppm with AT-Cut crystals. Most may be specified with either 5.0 or 12.0 Volts supplies.
We offer a full range of Sine Wave Output OXCOs and Square Wave Output OCXOs in various packaging configurations and specifications, most with EFC voltage control as standard.

We manufacture military specification crystals and oscillators for defence and aerospace applications, including:
• Through-hole crystals • Surface Mounted Crystals • CX Miniature Crystals
• Swept Quartz Crystals • CR Military Specification Crystals with full QPL certification to MIL-3098 available, and quality control in accordance with MIL-C-45208 and MIL-Q-4858.
• HC35 / TO5 Crystals • Military Specification Oscillators - high reliability units in 8 or 14 pin DIL and SMD packages. 14 pin DIL packages are available with 4 or 14 pins
• Stratum III TCXOs and OCXOs conforming to environmental and stability requirements of IEC60679-1, STRATUM III.
Unless indicated otherwise, all products are RoHS compliant.
