Vaunix Technology has released the new LPA-103V Lab Brick® Programmable Gain Amplifier, the latest addition to the LPA series designed to bring laboratory-grade gain control to engineering test benches, automated test systems, and production environments.
The LPA-103V operates from 0.5 to 10 GHz with a 30 dB gain control range and 0.1 dB step size, delivering calibrated, repeatable precision that engineers can count on whether working on signal conditioning, receiver testing, or automated RF characterization.
"The LPA-103V reflects everything we've built the Lab Brick brand around — affordability, reliability, and the kind of functionality that used to require much larger, more expensive equipment," said Dennis Flanders, Director of Sales and Marketing at Vaunix. "Whether it's on a bench in an R&D lab or integrated into an ATE rack, the LPA-103V gives engineers precise gain control without the complexity or the cost."
The LPA-103V connects via USB or Ethernet, offering engineers maximum flexibility in how they deploy and control the device. The USB interface uses a native HID connection, eliminating the need for kernel-level drivers and making the amplifier immediately usable on Windows, Linux, and low-cost embedded platforms. The Ethernet interface supports both Static IP and DHCP configurations, includes password protection for security, and enables Power-over-Ethernet (PoE) to simplify cabling in rack and remote installations. USB-PD and external DC supply options round out the power flexibility.
For programming, the LPA-103V supports fixed gain, swept gain ramps (unidirectional or bidirectional, one-time or repeating), and fully custom gain sequences. A Windows GUI and WebUI are included for immediate out-of-the-box use, while developers can take advantage of Windows API DLL files, Linux SDK, LabVIEW drivers, Python examples, and more to build custom automated workflows.
Key features of the LPA-103V include:
- 0.5-10 GHz frequency range with calibrated gain accuracy better than 0.25 dB at room temperature
- 0.1 dB step size with up to 30 dB of gain control range
- USB (HID) and Ethernet control - no kernel drivers required
- Powered by PoE, USB-PD, or external DC supply
- Fixed gain, swept gain, and programmable gain sequence modes
- Includes Windows GUI, WebUI, Windows SDK, Linux SDK, LabVIEW driver, and Python examples
- Expansion bus for linking multiple units under single-point control
- Compact 4.0 × 3.0 × 1.0 inch form factor
The LPA-103V is well-suited for engineering and production test labs, automated test equipment, and any application requiring precise, repeatable RF gain control across a wide frequency range.
