5G millimeter-wave radar development platform to accelerate development of broadband networking applications

Analog Devices' mixed signal front end AD9081/AD9082 and synthesizer ADF4371 accelerate the development of your broadband networking applications.

Giga Farm, an alliance partner of Analog Devices, 5G millimeter-wave radar development platforms, including FMC boards and clock generators using these products.

This article provides an easy-to-understand explanation of the platforms and devices that accelerate the development of 5G, millimeter-wave, and radar.

5G millimeter - wave radar development platform

Development Platform Configuration

This development platform consists of the following boards :

  • GRF-AD908x-FMC : FMC board equipped with AD9081 or AD9082
  • GIGA-PLL : Signal generator with ADF4371 (provides 6.11 GHZ and 768 MHZ clocks for system use)
  • GIGA DAQ : FMC host board (communication with ESD 204 interface of AD9081/AD9082)
  • GIGA SOC : platform processor (can switch between AD9081/AD9082 APIs on Linux)

Broadband FMC boards : GRF-AD9081-FMC/GRF-AD9082-FMC

The GRF-AD9081-FMC and GRF-AD9082-FMC are ultra-small multi-channel gigabit sample AD/DA FMC boards. AD9081/AD9082 on the board can be controlled by a dedicated API provided by Analog Devices.

This FMC board is a product that can be used in a wide range of applications, such as the development of research, analysis and test equipment, as well as the integration into wireless devices such as 4G LTE and 5G millimeter-wave wireless communication systems.

Since AD9081 and AD9082 are very high-performance products, they require a considerable amount of development resources to use them. The FMC board provided by Giga Farm solves these problems, because know - how is required for handling the high-speed JESD204 interface.

VCO Integrated Microwave Broadband Synthesizer ADF4371

The ADF4371 on the GIGA-PLL is a synthesizer with a wide continuous RF output range of 62 MHz to 32 GHz and the following excellent features.

  • Ultra - low FOM (normalized phase noise floor) : -234dBc/Hz
  • High phase frequency detection (PFD) function : up to 250 MHz
  • Minimum reference spurious : less than - 100 dBc (typical value)
  • Low VCO phase noise (-134dBc/Hz, 1 MHz offset at 8 GHz operating frequency)
  • Minimum combined phase noise (jitter) : less than 36 fs (10 GHz)
  • Integer boundary spurious (-90dBc, offset from integer channel to 960 kHz)
  • Built-in tracking filter for harmonic removal

This ADF4371-based GIGA-PLL is available as an ever-smaller signal generator that provides multiple outputs from the GHz clock to the millimeter-wave clock required by JESD204 devices. The GIGA-PLL can be purchased separately.
