Mini-Kits has a number of DDS Kits that include everything that you need to built your own DDS. The AD9851 DDS Kits are more suitable for use as a basic Signal Generator, Sweep Generator, or as a VFO for a Radio project. The AD9954 HF-DDS Kit is more complex, & is suited to building a high performance Radio Receiver or Transceiver project.

All the Kits & Parts that make up all the DDS Kits are available separately so that you can purchase the Kits & Parts that you require to suit your own project.

DDS SWEEP GENERATOR KIT

Sweep Generator Kit suitable for aligning & testing equipment. The Kit uses the Basic EME85 DDS Kit with the addition of a EME159 Control Board & 4x4 Keypad. The Kit uses modified DDS software to produce a Signal Generator, Sweep Generator function, & RF Power Meter using the optional RF Power Head Kits.

The EME159 Control board Kit 3, 45x45mm along with a 4x4 Keypad is suitable for controlling all functions of the Sweep Gen Kit. Functions including Frequency tuning, Step Size, Calibrate, Memory, Sweep Direction, Sweep Start Stop, Sweep speed, Fast Sweep, VFO/Sweep mode. 

Up to 11 Sweep Generator Memories, start, stop frequency, & sweep rate can be programmed. Refer to the Sweep page for more information.

The Kit comes complete with professionally plated through hole PC boards with solder masks.

The Knob1 to suit the EC12E encoder is optional but is included in the SWEEP KIT1 & is a high quality 28mm Knob with a locking collet, & press fit cap. It suits the EC12E 6mm Diameter shaft

Specifications Sweep Generator Kit:

1/ Frequency Range 0Hz to 60MHz ( AD9851 Chip )

2/ Frequency Resolution 1Hz

3/ Frequency Step Size 1Hz, 10Hz, 100Hz, 1kHz, 10kHz,100kHz, 1MHz, 10MHz, 100MHz, 1GHz

4/ Calibration / Adjustment Menu to set all options & settings without having to reprogram the PIC with a computer.

5/ RF Output typically +7dBm

6/ Slow sweep mode, 10Hz to 67kHz Second. Fast sweep mode, 12kHz to 20MHz Second.

THE SWEEP KIT DOES NOT HAVE A TRIGGER OR SYNC OUTPUT TO SUIT THE X INPUT OF AN OSCILLOSCOPE.

Refer to the Software Notes for more detailed information & Use, Download the Sweep Readme document.

This Kit can be changed to a DDS VFO Kit by simply buying a replacement PIC microcontroller PIC16F628DDS2.2. See the DDS VFO Kit Above.

 

 

Please Note that the above picture shows the EME85 KIT with optional OSC3/4 Osclillator module fitted.

500MHz POWER HEAD KIT

The Power Head is designed to be used in conjunction with the DDS Sweep Generator Kit, but can also be used with a Multimeter for simple RF Power measurements. The Kit uses the AD8307 Logarithmic Amplifier that allows RF measurement from DC to 500MHz. A PIC microprocessor is used to convert the analogue DC volts to I2C data & clock, to be read by the Sweep Generator Kit. All calibration data is stored in the PIC processor.

Specifications:

PCB Dimensions: 60x22mm 
Supply Voltage: +7 min to 14v max  @ 15mA max
Maximum Input: +26.5dBm ( Recommend +20 Max )
Dynamic Range: -75 to +17dBm ( 92dB +/-3dB AD8307 )
Bandwidth: DC-500MHz AD8307
Resolution: 0.25dB Minimum ( PIC A-D 1024 )
Output Linearity: +/- 1dB DC-500MHz

Refer to the Software Notes for more detailed information & Use, Download the Sweep Readme document.

7GHz POWER HEAD KIT

The Power Head is designed to be used in conjunction with the DDS Sweep Generator Kit, but can also be used with a Multimeter for simple RF Power measurements. The Kit uses the LTC5508 Logarithmic Amplifier that allows RF measurement from 300MHz to 7GHz. A PIC microprocessor is used to convert the analogue DC volts to I2C data & clock, to be read by the Sweep Generator Kit. All calibration data is stored in the PIC processor.

Specifications:

PCB Dimensions: 60x22mm 
Supply Voltage: +7 min to 14v max  @ 15mA max
Minimum Input: -27.5dBm
Maximum Input: +12.5dBm
Dynamic Range: 40dB
Bandwidth: 300MHz to 7GHz
Resolution: 0.2dB Minimum ( PIC A-D 1024 )
Output Linearity: Not Linear ( set in software )

A replacement PIC16F648A with Sweep Software will have to be fitted to the DDS board to suit the New 7GHz Power Head Kit, as it requires more memory space for the calibration menus. All previous Sweep Kits will need a replacement if you want to use the new 7GHz Power Head Kit.

The 7GHz Power Head Kit will require test equipment to align as the LTC5508 chips have too large a variation for it to be accurate at all power levels & frequencies with the standard software calibration.

Refer to the Software Notes for more detailed information & Use, Download the Sweep Readme document.

Accuracy depends on the test equipment used to calibrate the powerhead. We were able to calibrate a power head within 0.2dB compared to a Keithley 3500 RF Power Meter.

 

PIC CONTROLLER KIT

This Kit has primarily been designed as a PIC Micro controller & interface for the New HF-DDS Kit, but can be used as a general purpose Micro controller board using your own software.

The board allows for interfacing of a 4x4 Keypad, LCD Display, & various input & Output circuitry using onboard Headers.

The Kit uses a powerful PIC18F4520, & most Pins are available on connections around the outside of the chip .

The Microcontroller can easily be programmed using the Microchip PICKIT2 programmer connected to the IDC2 programming Header on the board.

What the Basic Kit Includes: Includes PC Board & all onboard electronic components, & 16 Pin IDC plug/socket & 25cm ribbon cable. The Basic EME150 KIT1 does not include the EME150/CONN Kit, or RS232 Kits as listed below.

Flash Memory: 24LC256 32k onboard chip
Clock: 10MHz onboard Crystal
Data Interface: I2C Bus, RS232
Analogue Inputs: 10 bit A-D up to 3 inputs available onboard.
Programming Port: IDC2 using Microchip PICKIT2 or 3 programmer

It is not recommended that you try & solder the Microcontroller chip yourself unless you are confident that you already have experience to do this. Mini-Kits will not replace any damaged chips or PC boards.
