RF & Microwave Passive Components

Reliable, high-performance passive RF and microwave building blocks, sourced from an AS9120B-certified distributor. From waveguide bends and couplers to coaxial adapters and precision horn antennas, Emerges Lite supplies the passive components that route, split, terminate and radiate microwave energy in radar, satcom and communications systems.
Backed by manufacturing partners such as Vector Telecom, our passive range covers frequencies up to 110 GHz with the electrical performance and mechanical repeatability that demanding programmes require across Singapore and Southeast Asia.

Coaxial Components	Coaxial adapters and connectors, cable assemblies, terminations, attenuators, couplers	Interconnect and level control between modules and test equipment
Microwave & Millimeterwave Antennas	Standard gain horns, wideband horns, parabolic and feed antennas, near-field measurement probes	Transmit, receive and gain-reference antennas for comms, radar and test

Why Choose Emerges Lite for RF & Microwave Passive

AS9120B-Certified Distributor

Our AS9120B and ISO 9001 certifications, with IAQG registration, ensure quality, traceability and genuine components for mission-critical RF and microwave designs

Industries Served

Radar Systems

Weather, surveillance, marine and air-traffic radars depend on low-loss waveguide runs, directional couplers for power monitoring and precise antenna feeds. Our passive range supports both the transmit chain and the receive front end.

Test & Measurement

Standard-gain horns, calibrated attenuators, terminations and near-field probes give laboratories accurate, traceable references for antenna characterisation and system verification.

Satellite Communications

VSAT and satcom ground equipment need OMTs, feed horns and waveguide assemblies with tight VSWR to protect link budgets. Ka and Ku-band components support the higher frequencies now common in satellite links.

Defence & Electronic Warfare

Wideband couplers, adapters and antennas support signal intelligence, jamming and countermeasure systems where broad frequency coverage and rugged construction are essential.

Key Features & Benefits

Broadband coverage from below 1 GHz through to 110 GHz across S, C, X, Ku, K, Ka, Q, U, V, E and W bands.
Monopulse comparators and complex feeds for direction-finding and tracking systems.
Low insertion loss and tightly controlled VSWR for minimal signal degradation in the passive path.
High isolation and directivity in couplers, magic tees and OMTs for clean signal separation and monitoring.
Precision-machined waveguide with repeatable flange interfaces for reliable, low-loss joints.
Power-handling options from low-power laboratory devices to higher-power transmit components.
A single-source signal path, waveguide, coaxial and antenna, that simplifies specification and procurement.

What Our Clients Are Saying

Emerges has helped us increase the reliability of our products with their certified power convertors and RF components. We are very happy with the quality and service from them.

Timothy Wills

We often find that getting reliable components very difficult but with Emerges, and their supply of Teledyne components, we have really very little concerns in quality. Thank you for your assitance with our last few projects and looking forward to working on more in the future

Pedro Torres

Looking for a certified Teledyne RF component supplier and we came across Emerges. They are extremely professional and their turnaround time from ordering to delivery was amazingly fast. Thank you Richard and team!

Frequently asked questions

Sylatech supplies custom RF and microwave engineering, including slotted array and flat-plate antennas, monopulse comparators and feeds, waveguide components (cast bends, twists, flanges, couplers, OMTs, magic tees and adapters), power dividers/combiners and rotary joints, plus precision investment castings and CNC-machined parts.

Yes. Emerges Lite represents Sylatech across Singapore and Southeast Asia as an AS9120B-certified and IAQG-registered distributor, providing regional engineering and procurement support with full traceability.

Sylatech's RF and microwave design experience covers S, C, X, Ku and Ka bands to 40 GHz across antennas, feeds and passive waveguide components.

Investment casting, or lost-wax casting, produces thin-wall, lightweight metal components with complex geometry. For RF hardware it allows cast waveguide bends, feeds and housings that are lighter and often more cost-effective than fully machined parts, which is valuable in airborne and space systems.

Yes. Our experienced engineering team provides end-to-end technical support, including component selection, system integration guidance, sampling requests, and datasheet access for the entire Teledyne e2v HiRel range.

Sylatech serves aerospace, space and defence as its core markets, and also supports medical, automotive, rail and scientific sectors, including particle-physics and laboratory applications.

Yes. Sylatech offers an integrated custom design service, using CST simulation and SolidWorks to convert an electrical specification into hardware, then manufacturing it in-house through casting, machining, assembly and full electrical testing.
