Employ powerful RF solutions

Aspen Electronics is now offering high power directional couplers manufactured by IF Engineering. These compact devices are ideal for RF applications where RF or microwave incident and reflected power needs to be sensed, sampled and measured with minimal disturbance to the transmission line.

Part of the C4 range of directional couplers, these high power versions offer power handling from 25 to 150W continuous wave (CW), covering frequency ranges up to 1GHz. Coupling values range from 14 to 40dB, while directivity values range from 15 to 30dB, to give the least measurement uncertainty.

Voltage standing wave ratio (VSWR) figures are also low, from 1.1:1 to 1.4:1, which helps to minimise the effects of return loss and thereby measurement accuracy.

Typical applications include high VSWR amplifiers and fold back devices, as well as for power levelling and signal monitoring systems in TETRA and other VHF/UHF wireless communications systems operating up to 1GHz.
