The latest and most advanced Lab Brick digital attenuator from Vaunix, the LDA-602Q, covers 200 MHz to 6 GHz and features bidirectional fixed attenuation and swept attenuation ramps and fading profiles. The LDA-602Q provides up to 120 dB control range, 0.1 dB step size and an input IP3 of over 55 dBm. Maximum input power handling is +28 dBm. Each RF port of this 4-port attenuator is matched to 50 Ω, with a typical VSWR of 1.3:1. Fast switching within 15 μs is typical, and the attenuator is designed to operate reliably from −10°C to +50°C.

The LDA-602Q is compact, fitting into a single standard rack unit with well-spaced 50 Ω SMA female connectors for each RF port. Power and control are provided through a standard USB type-B female interface. Two counter-bore holes streamline mounting and placement.

This digital attenuator can be used in numerous applications, including UHF to C-Band wireless automated test equipment; MMIO testing; and LTE, Bluetooth and SATCOM fading simulators.

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