AD9850 DDS Signal Generator Module 0~55MHz Shortwave radio Wave band for HAM Radio SSB6.1 Transceiver VFO SSB

AD9850 Module DDS Signal Generator 0~55MHz Shortwave radio Frequency Wave band for HAM Radio SSB6.1 Transceiver VFO SSB

Features:

This is a 0~55MHz DDS Signal Generator. It is based on AD9850 chip and is very easy to operate.

Supports 0~55MHz continual adjust at 1Hz step.

Input 12V (Seller’s Note: We are also providing a simplified version, with input 8~9V)

With direct digital input frequency

With audio volume potentiometer

With amp. gain potentiometer

With AGC potentiometer

S-LED display

Standing Wave-LED display

Keys & Connection interfaces:

ENC: Encoder switch

MEM: Switch for memory mode

VFO: Transfer from VFO A to VFO B, or from VFO B to VFO A.

SSB: Working mode change: circulate from USB, LSB, AM, CW, and on and on…

RIT: Fine tuning to receiving frequency

CAL: Set functions

KB-1 and KB-2 have common shared pin, but is not GND.

How to operate:

Press CAL, power on, then we enter setting screen. Let go/release CAL.

A: ENABLE 6XREFCLE: setting chip clock mode, adjust frequency encoding setting. AD9851 set to 6-multiply frequency, AD9850 set to 1multiply frequency. Press CAL then quickly release to enter next step B.

B: DDS-SYSTEM-CLK: Chip working frequency setting. Use encoder switch to adjust value. Operate in accordance with STEP key. AD9851 set at oscillator 6-multiply channel, AD9850 set at actual output of oscillator. Press CAL then quickly release to enter step C.

C: MIN_RX_DDS_FREQ: Setting minimum working frequency. Use encoder switch to adjust value and in accordance with STEP key. Press CAL then quickly release to enter step D.

D: MAX_RX_DDS_FREQ: Setting maximum working frequency. Use encoder switch to adjust value and in accordance with STEP key. (Smaller than 60MHz would be OK ). Press CAL then quickly release to enter step E.

E: SSB_OFFSET: Fine tuning for SSB working mode. Use encoder switch to adjust value and in accordance with STEP key. Press CAL then quickly release to enter step F.

F: CW_OFFSET: Fine tuning for CW working mode. Use encoder switch to adjust value and in accordance with STEP key. Press CAL then quickly release to enter step G.

G: OFFSET_FREQ: Setting of offset Frequency. e.g, set to 9MHz or 10.7MHz, use encoder switch to adjust value and in accordance with STEP key. Press CAL then quickly release to enter step H.

H: MULTIPLIER: multiply setting for frequency. Should be set as 1, press CAL then quickly release to enter step I:

I: Screen displayes word “SAVE”, automatically save the above setting, and returns to normal working.

Notes:

DDS SYSTEM CLK: can use frequency tester to get 30MHz oscillator, multiply the tested value at 6, then put the multiplied value here. If using AD9851, make initial setting at 180000000.

OFFSET FREQ: can be set as + or – . Rotate encoder switch to change value, press STEP key, then rotate encoder switch to adjust step. Minimum working frequency plus (+) offset frequency should be high than 0 (zero).

Frequency display:

RX = MULTIPLIER x (RX_DDS_FREQ + OFFSET_FREQ)

TX = MULTIPLIER x (RX_DDS_FREQ + OFFSET_FREQ + TX_OFFSET_FREQ)

The frequency programmed into the DDS, is calculated as shown below.

RX = ABS(RX_DDS_FREQ)

TX = ABS(RX_DDS_FREQ + TX_OFFSET_FREQ)

RX_DDS_FREQ, MIN_RX_DDS_FREQ, MAX_RX_DDS_FREQ, TX_OFFSET_FREQ & OFFSET_FREQ

Examples:

1. DDS output range 30~40MHz:

MIN_RX_DDS_FREQ MAX_RX_DDS_FREQ OFFSET_FREQ RX Frequency display range.

30 MHZ 40 MHz 100 MHz = 130 MHz to 140 MHz. Note 1

30 MHZ 40 MHz -10 MHz = 20 MHz to 30 MHz. /

-40 MHZ -30 MHz 170 MHz = 140 MHz to 130 MHz. Note 2

-40 MHZ -30 MHz 60 MHz = 30 MHz to 20 MHz. /

2. Setting FT180A with DDS:

ENABLE RPT NO

X6 RECLK X6

DDS SYSTEM CLK 180M

MAX DDS FREQ 65M

MIN RX DDS FREQ 10.701M (Offset frequency + RIT frequency)

MAX RX DDS FREQ 60M

TX OFFSET FREQ 0

MAX RIT OFFSET 1K (RIT frequency)

OFFSET FREQ – 10.700M – (Offset frequency)

MULTIPLIER 1

Package includes:

1 x DDS Signal Generator

Interface function:

1: 12V Input

2: 12V Output

3: Standing Wave Test Signal Input (Shared GND)

4: Manual Adjust for Gain/increase

5: Bandwidth Power Adjust (Shared GND)

6: Audio Volume Adjust

7: To PTT & CW of mainboard

8: Mode & Band Control for corresponding mainboard

9: DDS test power supply (PLS DON’T CONNECT)

10: Manufacturer test use, no other features

Packing for such a product could be tougher-broken 2 buttons are repaired, but it's necessary for me-I expected at least in a box.
