	Logus Microwave are manufacturers of a wide range of co-axial and waveguide mechanical switches covering the range DC to 40 GHz. The waveguide switches include double-ridge and tri-band types. Failsafe and latching actuators. Indicators and optional actuating voltages.
	MBF Microwave manufacture a full range of mechanical co-axial switches. SPDT to SP10T, with options of various RF connectors and actuator voltages, failsafe and latching, indicators, TTL drive. Replacements for Dynatech, DB Control and other manufacturers' types.
	Microwave Dynamics supply microwave frequency sources. They manufacture phase-locked and free-running dielectric-resonator oscillators, amplifiers and multipliers for frequecies up to 60 GHz. These feature the best noise stability and reliability performance available. Of particular value is their ability to provide DRO-based sources at frequencies below 3 GHz by frequency division. They are an ISO9001 company.
	Microwave Industries make low-noise and medium power microwave amplifiers covering 0.5-60 GHz in narrow, octave and multi-octave bandwidths. They feature a range of low-gain isolation amplifiers for active buffering where ferrite components are too large or cannot cover the bandwidth. Will make custom units and replacements for obsolete manufacturers amplifiers.
	Omniyig have been specialising in YIG-tuned filters, oscillators, discriminators and multipliers now for over 25 years. They also have technology-related products of schottky and tunnel detectors, PIN and schottky power limiters and harmonic generators. Their products can be found in the majority of key EW programmes. Pass and reject filters with up to 10 resonators. 1x1x1/2 ins and permanent-magnet biassed types. Omniyig have always provided the best tuning linearity and lowest spurious performance available.
	Paciwave are a leading manufacturer of PIN switches and related devices such as analogue/digitally-controlled variable attenuators and sub-systems containing amplifiers, mixers and filters. Standard SPST to SP5Tswitches in reflective and absorbtive versions all have TTL drive . Packages alternatives are SMA, pin or drop-in. High power and high isolation options. Paciwave will make custom products.
