HackRF One SDR 1 – 6000 MHz

HackRF One

The HackRF One is a test equipment module for RF related experiments and measurements which covers a frequency range from 1 to 6000 MHz. It is used for experiments and measurement setups with open source programs for SDRs, own software development for radio communications and measurements in amateur radio. The hardware was developed by Michael Ossmann (USA) as an open source device, backed by a strong Kickstarter funding project. It is now sold as a commercial product as well.

The system covers a wide frequency range from 1 to 6000 MHz, and covers many licensed and unlicensed as well as ham radio bands. The hardware offers a maximum sample rate of 20MS/s, which is sufficient to measure even wide band signals like WFM, DECT, Wifi and others. The ADC works with 8 bit data width and offers a dynamic range of 48dB. The digitised I/Q data is handled by a Xilinx CPLD and an integrated ARM Cortex processor. Due to the design and component selection the device supports only half-dulplex operation.

The entire circuitry is designed for low power consumption, supply is done over USB only. The board has a Micro-B USB socket, a suitable cable is included. To synchronise several HackRF One boards, the system offers connectors for clock input and output. These signals can be used to use multiple boards in parallel, for example for measurements on MIMO systems or full duplex systems. Two push buttons and several diagnostic LEDs are provided for easy operation.

The PCB is professionally manufactured with 4 layers. All components are SMD parts. To support own hardware development and extensions, many signals are available on jumper sockets. These connectors offer GPIO pins as well as parameter in- and outputs from the CPLD. A JTAG connector can be used to program the ARM Cortex processor.

HackRF One Circuit Description

HackRF 1 Block Diagram Frontend HackRF One Frontend Block Diagram

Please refer to the frontend block diagram. The HackRF One board is characterised by a very high flexibility when choosing the signal path. RF switches at all critical junction points allow the selection of various components, based on user programming.

After the antenna input two MGA-81 GaAs MMIC amplifiers follow, one serves the input, the other the output path. The amplifiers ICs can be selected in and out of the signal path by RF switches (SKY13317).

The amplifier block is followed by a low-pass and a high-pass filter, which can be used to limit the signal in either path (input/output). After the filter the signal arrives at an RF mixer RFFC 5072. This mixer can be used up to 6GHz. The signal is mixed up or down, depending on user programming and finally fed to the baseband circuitry. Mixer and filters can be bypassed by further RF switches, allowing the IF signals to be switched directly to the amplifiers or directly to the antenna.

As baseband chip a Maxim MAX2837 component is used, which covers a frequency range of 2.3 to 2.7 GHz. The chip uses monolithic filters which provide for a very linear signal and a low noise figure. The IQ data is then passed to an ADC/DAC chip Maxim MAX5864. This ADC as well as the DAC uses has 8 bit resolution. A maximum sample rate of 20MS/s is supported by these converters. The digital signals are finally passed to a Xilinx XC2C CPLD. The entire system and all interfaces are controlled by a powerful ARM Dual Core Cortex processor (NXP LPC4320). The board further supports 1MB flash memory.

Software for the HackRF One Board

Currently (Autumn 2014) the HackRF One board is working with 'SDR-Radio', 'GNU Radio' and 'SDR#'' (SDR Sharp). Due to the open source and license fee free nature of the project, other software project can join at any time. Several authors already have announced their support for the HackRF One. Up to date information about software is found on the manufacturers Wiki site.

18. Aug. 2014: Now the software SDR-Radio by Simon Brown supports the HackRF Board (from version 2.x on).

SRH-789 SMA Antenna 90 – 1100 MHz

Bild SRH-789 SRH-789

The SRH-789 is a wide band telescopic antenna for scanners and similar devices. The adjustable frequency range is from 90 to 1100 MHz, the resonant frequency is set by changing the length of the telescope. Retracted length 20cm, fully extended length 80.5cm. A helpful table for various lengths and frequencies is printed on the loermost element of the antenna. The connector is SMA male, with locking nut, which allows the antenna to be adjusted in any position on the SMA socket. A knuckle helps adjusting the antenna vertically or in any other direction.

Bonito Loop ML-200

Mega Loop ML-200 ML-200 RX Antenna

The Bonito ML-200 is a wide band active antenna for reception of long, medium and short waves as well as the lower VHF band. The antenna is is characterized by a small apcking size, low noise and excellent signal levels.

The ML-200 consists of a flexible, braided wire loop with large wire gauge. The loop is connected to the amplifier, both are installed by hanging the wire to the wall, into a window, in a tree or on another suitable supports. The amplifier is supplied over the coaxial cable (not included) from a supplied Bias-T. This Bias-T has connectors for an external supply voltage as well as a socket for a USB cable. The voltage can range from 5 to 15 V. The USB connector makes the antenna very well suitable for portable operations with a computer.

Despite the high amplification, the ML-200 has a very low noise level, as comparisions to other active antennas have shown. The antenna can be used from long wave (9 Khz) up to the lower VHF range of 200 MHz. The amplifier has a very high 3, order intercept point of +40dBm. This results in a very high distortion free blocking dynamic range. The amplifier is protected by a twofold overvoltage protection. With this protection the antenna not only survives a thunderstorm but can also be used in vicinity to transmitting antennas, for example in the garden of a radio amateur or on a sailing yacht.

With the small packing size and the USB power supply the ML-200 is very well suited to accompany you in a vacation. For example the antenna can be easily installed with two suction cup holders in a window. The coaxial cables are not supplied because most customers require different lengths. WiMo does provide several ready made cables, and can also manufacture a cable tailored to your requirements.

Packing size 20 x 20 x 5cm, weight 480 g. Connector on amplifier: BNC, HF-Connectors on Bias-T: 2x BNC. Requires additional DC cable or USB cable for power suply. Supply voltage from 5 to 15V DC, max. 40mA.
