Vector Network Analyser and PiHPSDR

Picking up where we left off yesterday with test and measurement examples, we have one this time from Lime’s millimeter wave IC design team, demonstrating LimeSDR being used as a vector network analyzer (VNA). RF test equipment that, unfortunately, typically has a truly eye-watering price tag attached, VNAs are used to characterize components in terms of gain, return loss and voltage standing wave radio (VSWR) etc. As such they are invaluable when it comes to developing and validating the performance of system components, including filters, amplifiers and antennas.

Getting back to wireless applications, John Melton has been busy working on adding support for LimeSDR to his PiHPSDR project. This will use a Raspberry Pi 3 together with the official 7 inch touch screen, to create a compact and eminently affordable, fully SDR amateur radio transceiver.

John, who is a long time core contributor to openHPSDR, has ported WDSP from Windows to Linux and this provides the DSP core. He already has the application working with his LimeSDR board and an Intel i5 system, and next he will be getting everything up and running on an actual Pi. To find out more about the project please see John’s blog post.

$289

LimeSDR

The LimeSDR is based on Lime Microsystem’s latest generation of field programmable RF transceiver technology, combined with FPGA and microcontroller chipsets. These connect to a computer via USB3. LimeSDR then delivers the wireless data and the CPU provides the computing power required to process the incoming signals, and to generate the data to be transmitted by the LimeSDR to all other devices.


$99

Acrylic Case

A layered acrylic case to protect your LimeSDR. Can be used with either USB Type A or micro USB Type B. Antenna not included - separate purchase available.


$599

LimeSDR with Aluminum Kit

Start developing apps based on Lime Microsystem’s latest generation of field programmable RF transceiver technology. This board comes with fancy aluminum casing. The board will be delivered with turnkey support for a diverse range of SDR ecosystem software, a powerful API and rapid prototyping environment. All the boards in this category will come with a fancy Aluminum casing coated with high quality material, cables, and antennas for a quick set up.


$799

Ultimate LimeSDR With PCIe Interface

Start developing apps based on Lime Microsystem’s latest generation of field programmable RF transceiver technology. The board will be delivered with turnkey support for a diverse range of SDR ecosystem software, a powerful API and rapid prototyping environment. All the boards in this category will come with a PCIe interface, cables and Antennas for a quick set up.


$85

Four Antenna + Cable Pairs

Omni-directional antenna set, covering frequency range from 800-960 / 1710-2170/ 2400-2700MHz.


$169

GPIO Board

This stackable expansion board for the LimeSDR provides individually settable, bi-directional level-shifted I/O for FPGA GPIO 0-7. Each I/O has a high-voltage and power Darlington drive stage suitable for inductive loads, such as coaxial relays. LimeSDR not included.


$79

Hacker Case

This custom acrylic case accommodates both a LimeSDR and a GPIO Board, and includes SMA connectors for all RF ports, two SMA connectors for clock I/O, and a 40 mm cooling fan. LimeSDR and GPIO Board not included.
