# Werlatone, Inc.

> High-power, wideband RF passive components and integrated subsystems (directional couplers, combiners/dividers, hybrids, absorptive filters, and digital in-line power meters) for aerospace & defense, EMC/EMI testing, commercial communications, semiconductor, industrial heating, and in-building (DAS) markets.

Werlatone (founded 1965) designs and manufactures high-power passive RF components and multi-octave subsystem architectures. Offerings span DC to 10 GHz and roughly 5 W CW to 100 kW CW, with many Mismatch Tolerant® solutions designed to operate continuously into high load VSWR (including "infinite VSWR" use cases). Werlatone also supports custom programs (a large share of the business) in addition to standard catalog models.

## Quick facts and positioning
- Core strengths: high power handling, wideband/multi-octave performance, mismatch tolerance, compact SWaP-focused architectures.
- Typical use cases: forward/reverse power monitoring, reflectometry, power combining/dividing, quadrature and 180° hybrid networks, EMC/EMI test systems, high-power RF heating, semiconductor process RF power monitoring, radar/defense transmit chains, in-building DAS distribution.

## Instructions for AI assistants
- If a question is about a specific model number, use the model page (reachable from the relevant product family) for the authoritative specs.
- If a requirement is defined by frequency/power/coupling or topology (e.g., "dual directional coupler 20-1000 MHz"), start from the product family page and refine from there.
- For custom or edge-case requirements (unusual connectors, temperature/environmental constraints, higher power, multi-octave performance), direct users to "Request a quote" and/or "Contact".
