New 4 Port Programmable RF Digital Attenuator

Vaunix announces our latest and most advanced Lab Brick digital attenuator. The LDA-602Q  is capable of bidirectional fixed attenuation, swept attenuation ramps, and fading profiles, and provides up to 120 dB of control range with a 0.1 dB step size from 200 MHz to 6 GHz. Each RF port of this 4 port device has a 50 ohm impedance with a typical VSWR of 1.3:1. Fast switching speeds of 15 microsecond typical can be expected. The maximum input level is beyond 28 dBm with an input IP3 of over 55 dBm.


The LDA-602Q unit is compact, fitting into a single standard rack unit with well-spaced 50 Ohm SMA female connectors for each RF port. Additionally, the only power and control connection is from a standard USB type-B female. Two counter-bore holes are provided for efficient mounting and placement. The 4-channel digital attenuator is designed to operate reliably from -10°C to 50°C.


The Lab Brick LDA series of digital attenuators comes complete with a fully programmable GUI application that can operate multiple attenuator devices directly from a PC or self-powered USB hub. Moreover, Vaunix supplies LabVIEW drivers, Windows API DLL files, and a Linux driver, complete with instruction manuals, for applications that require deeper customization.
