Variable
Our programmable attenuators offer a wide selection of solid-
state, mechanical and edge line designs. These are available to a
maximum attenuation level of 127dB in step sizes ranging from 0.1
to 10dB. Frequency ranges from DC-40GHz
Manual step attenuators offer low SWR and accurate repeatability.
Beamformers Beamformers are networks that perform vector manipulation of two or
more inputs to produce two or more outputs which when fed to or from
an antenna array represent coordinates in a three dimensional system.
They feature:- excellent loss, compact design, wide frequency range
(10MHz – 18GHz) and excellent phase/amplitude accuracy.
Examples of beamforming networks include; Butler Matrix and
Phase Arrays.
RF & Microwave Components Bias Tees and Bias Tees allow the insertion of DC voltages into a signal path
without disrupting the existing signal in that path.
DC Injectors There are a number of model types available covering General
Purpose, High Current, Broadband and Pulsed.
