Radio Frequency and Switching Products Following the acquisition of Raven Research Ltd, Drumgrange can supply a wide variety of RF products, either as part of a larger solution provided by Drumgrange, or to other system integrators. Multicouplers The Drumgrange range of Multicouplers provide comprehensive protection from high-level signals and electrostatic discharge.
• • • •
Frequency Range 1.5 MHz to 2 Ghz Choice of Standard Control Protocols AC/DC power options Wide choice of standard and non-standard connectors
Non Blocking Matrices & Switches Drumgrange make a range of non-blocking matrix switch units for switching/routing off-air signals to receivers. • • •
Excellent RF Performance with low noise figure and high Dynamic range Choice of standard control protocols Ancillary units for integration of Antenna Matrix Switching Systems HF Switching Matrix
Masthead Pre-Amplifiers
A range of wideband masthead pre-amplifiers to cover the VHF/UHF bands are available. These pre-amplifiers greatly improve the RF sensitivity of fixed-site and transportable systems, whilst preserving maximum dynamic range. • Low noise figure for maximum sensitivity • High 2nd Order and 3rd order intercept points for maximum dynamic range • Input Protection against high level signal, lightning and EMP • Bias 'T' for power through RF cables • Amplitude equalisers for long cable runs over wide frequency ranges Radio Direction Finding (RDF) Drumgrange has a wide range of RDF products: • • • •
Land mobile, covert RDF systems for radio regulatory enforcement or radio interception Fixed Site VHF/UHF radio direction finding Fixed Site HF radio direction finding for single sight location Shipboard RDF for surveillance and ESM
3G Jammer
RF Components Drumgrange supply a range of general RF products. The products listed below cover a wide range of frequency bands and have different types of connector configurations. These components can be re-configured to address any customer requirements.
