AD9850/51 DDS CONTROLLER KIT

This Kit has primarily been designed as a PIC Micro controller & interface for the New AD9851 DDS VFO & I/Q DDS Kits. The Kit can be used as a general purpose Micro controller board to suit your own DDS, or other Project using your own software.

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

The Kit is designed to use a PIC16F648, & most Pins are available on the header connections around the outside of the board. Many other PIC16F6XX series chips can also be used on this board.

What the Basic Kit Includes: The Kit includes everthing shown in the pictures excluding the EME170/CONN Kit, KNOB2, or any software.

The Basic EME170 KIT1 comes complete with a blank PIC16F648A Microcontroller, a 16 Pin IDC plug/socket & 25cm ribbon cable.

Please Note: That no software or Software support is included with this Kit. Mini-Kits can supply standard dd_synth_ver2.2x DDS software to suit the AD9850/51 DDS.

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.

Please Note: That no software or Software support is included with this Kit.

Specifications:

PCB Dimensions: 84x65mm 
Supply Voltage: +12v <50mA with no hardware connected
Microcontroller: Microchip PIC18F4520-I/PT 40MHz 32k flash
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.

 

BASIC EME150 KIT, with optional EME150/CONN & RS232 Kits

PIC OUTPUT EXPANDER KIT

This Kit is designed to expand the number of outputs from the PIC microcontroller on the EME150 PIC Controller board. The board is an option that can be used with the HF-DDS Kit, to control circuitry like band & filter switching, mode selection, AGC, IPO, RX/TX switching, & many other radio related functions. One board has 32 low current logic outputs that can be used to control relay drivers & logic circuits, & further boards can be connected together to increase the outputs to a maximum of 96 using the HF-DDS software.

Specifications:

PCB Dimensions: 44x65mm 
Supply Voltage: +5v <20mA if all outputs were on.
Logic: 4 x 74HC595 ( output 0 / 5volt )
Data Input: Data Latch & Clock

CONTROL BOARD 3 KIT

This Kit was designed to make it easier to mount a rotary encoder onto the front panel of a box, & for a wiring interface to a Keypad & LCD Display module. It is currently used with the New HF-DDS Kit. The Kit is also suitable for using with the Universal Wide band SP5055 PLL Kit. The Kit uses a low cost EC12E Rotary Encoder that requires a tuning Knob that suits a 6mm diameter shaft that is not included in the Kit.

Specifications:

PCB Dimensions: 45x45mm 
Encoder: ALPS EC12E

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.
