DBSpectra has launched the ACV2701J1 variable attenuator for operation in the 806 MHz to 861 MHz band. The device is used on a transceiver to vary the output power level—from 95.5% to 1% or less of full output power—without intervention of the original signal. The ACV2701J1 is rated at 50 watts and is available in versions that contain an integrated harmonic filter.
