Programmable Rotary Vane Attenuators Series 620 and Series 621

Two basic types of Programmable Rotary Vane Attenuators, Series 620 and 621, are available. The Series 620 has been extended to include models down to 3.22 GHz. The new Series 621 models offer an additional high resolution helical readout scale offering manual control.

High Speed Operation:

Programmable Rotary Vane Attenuators are fitted with a high speed drive motor capable of re positioning the attenuator from 0 dB to 60 dB (see note 1) in less than 1.1 seconds when driven by our dedicated Control Processors.


	WG10 to WG29	WG30	WG31	WG32	(260-400)	(325-500)
Attenuation accuracy	0 dB to 60 dB	0 dB to 50 dB	0 dB to 45 dB	0 dB to 40 dB	0 dB to 35 dB	0 dB to 30 dB
Attenuation accuracy	0.1 dB or 1% whichever is greater	0.15 dB or 1.2% whichever is greater	0.2 dB or 1.5% whichever is greater	0.3 dB or 2% whichever is greater	0.4 dB or 2.5% whichever is greater	0.5 dB or 3% whichever is greater

Operating temperature range: +5°C to +35°C (Refer to Flann for wider temperature range consideration)
Note 1: Customised models with extended attenuation ranges can be supplied. Please contact our Sales Team for further details.
