Introduction
Distinguished custo ers! We would like to thank you
for choosing the production of Russian co pany
Expert Electronics! While the production of new HAM
devices we tried to take into account all the wishes of
our clients and to i ple ent the in the ost
advanced anufacturing and digital techniques of
signal processing.
Now the develop ent of digital technologies as the
application to the HAM practice allows to i ple ent
the best hardware characteristics of digital
transceivers and receivers. Our experience in the
sphere of digital signal processing allows to pursue
the excellent sound quality and the opportunities for
clearing the signal fro noise.
The software ethods of hardware controlling allow
to configure the controlling of the receiver and the
transceiver flexibly based on your own preference.
Now in front of you is one of the ost advanced and
perfect receivers produced in the recent decade.
We would like to bring your attention a new
ColibriDDC receiver, which is produced in accordance
with the DDC technology. DDC technology eans the
usage of direct sa pling of signal fro the antenna
and the digital conversion of the signal down.
The principle is based on the digital sa pling of the
wide spectru of signals practically directly fro the
antenna, signal thinning and software signal bearing
“down the frequency”. The signal is software
processed. The necessary odulation type is decoded
and the i age of the panora a of the necessary
spectral band is also for ed. The known ethod of
the direct signal transfor ation fro HF to LF is used
as the basis. In distinction fro the previous
generation of SDR receivers and transceivers, where
the signal transfor ation of the orthogonal
(quadrature) signals was held on the hardware level,
the software bearing is applied in new receiver. It
allows to suppress the inactive sideband, carrier
frequency and i age channel practically ideally.
The band of the displayed frequency spectru in the
classical technology of the SDR- receipt with signal
conversion on the sound IF was bounded by the band
of signal conversion of the sound card. Now when the
whole spectru of the short-wave band is digitized, it
is possible to display any band within the digitization
li its.
But that is not all! The a ount of possible physical
receivers is not li ited by one receive path. In
ColibriDDC there were i ple ented 4 software
receivers and also there is an opportunity to
si ultaneously observe the whole SWB.
Absence of IF signal conversion and digital
de odulation algorith s allow to receive the
qualitative pure signal at the receiver's output.
Except onitoring with good visualization, the
receiver's controlling progra allows:
•to record the high qualified input signal;
•to record the air station in the frequency
bandwidth and to reproduce it later;
•choose any filter pass band fro 10 Hz to 20
kHz with a good ra p;
•control any odulation odes, including the
receipt of the radio stations of digital
broadcasting standard DRM (using third party
software).
With the introduction of new ColibriDDC receiver
ca e a new ti e for the radio a ateurs who work in
VHF. The receiver's software allows to watch the
presence and activity of the radio stations in VHF and
UHF bands with any odulation type and bandwidth
to 62 MHz.
Over the recent years the attention of a large nu ber
of radio a ateurs was attracted by the SDR the e.
During the previous several years there were found
both advantages and disadvantages of the classical
SDR-technology. The large ajority of the found
disadvantages was excluded by igration to the
technology of direct signal digitization. Now we can
declare that the receiver is ideal.
The big brands who produce the hardware for special
application are interested in DDC technology. So, for
exa ple, the SDR and DDC technologies are used in
obile co unication technology, ilitary
co unication technology, wireless network
hardware and that's not a full list.
So let's co e to the description of the ColibriDDC
receiver, which is offered by Expert Electronics.

3. Operation mode description
Receiver is ade on the basis of four-layer printed
circuit board of size L 110 х W 60 .
All the receiver's co ponents are ounted on the
board by the surface ounting and installed on the
upper layer. The process of board asse bling is fully
auto atized and is ade on odern high-tech
industries. All the receiver's functional parts are
installed on the board under the shields.
Asse bled board of the receiver is ounted into the
light anodize case fro alu iniu alloy. Hard case
protects the receiver fro external physical i pacts
and shade the board fro external electro agnetic
e issions.
Electric diagra of the receiver is given at the figure
below.
Receiver' s path consists of the following functional
units:
•Ant – antenna connector. Inputs the signals;
•LPF – low frequency filter with the 55 MHz
bandwidth. Filter allows to extract the first
Nyquist zone signal to exclude the receipt of
signals fro the other zones. This filter is
necessary if the receiver is used without
external band filters. LPF can be switched off.
In this case the signal goes bypass the filter;
•A – attenuator – 20 dB. Attenuator allows
to loss the signal to exclude the overload of
the receiver during the receipt of the power
signals. If the attenuator is switched off, the
signal goes bypass without loss;
•ADC – high speed analog-digital converter
(ADC) with the sa pling frequency 125 Msps
and the resolution 14 bit. ADC is the heart of
the receiver. It converts all the input radio
signals in the band 62.5 MHz into the digital
readouts for further digital processing;
•FPGA - field progra able gate array (FPGA).
Provides all the high speed operations of the
digital signal processing. The first down-
conversion is ade here. It can be so ehow
co pared with the first converter in the usual
superheterodyne, but all the operations are
held athe atically with the binary logic;
•MCU – icrocontrol unit. Passes the data into
the PC, receives data fro PC and controls all
the syste s of the Receiver;
•LAN – Local Area Network. Data exchange in
the Receiver is provided with the speed 100
Mbps over the local network. Such interface
exchange between PC and the receiver easily
allows to connect the receiver and/or use for
the connection the existing local network;
•PLL –built-in frequency synthesizer. Used for
the receipt of the ounting clock frequency
125 MHz for clocking the ADC. Two sources of
the reference signal (TCXO and external
reference oscillator with the frequency 10
MHz) can be used as the reference generator
for PLL;
•CXO – inbuilt te perature co pensated
crystal oscillator with the frequency 20 MHz.
This very stable oscillator with the
6

Expert Electronics ColibriDDC receiver
te perature instability 0.5 pp ;
• REF - connector for connecting the external
very stable oscillator with the frequency 10
MHz. According to the task and the
require ents to the frequency stability, the
necessary source of the reference frequency
can be used. It can be chosen in the Settings
of the controlling ExpertSDR2 progra ;
It should be entioned that the stability and
quality of the receiving signals depends on
the stability and phase cleanliness of the
reference frequency sources.
•EX C RL - connector for operating the
external devices. The receiver contains 7
powerful switches with open collector, which
can be configured by User in accordance with
the band. For exa ple, range band filter,
antenna switch, etc. can be controlled;
•DAC – digital-analog converter with the
resolution 24 bit. This unit akes the reverse
transfor ation of the digital signals into the
analog audio signal. This unit for s the sound
in the receiver's bandwidth and sends to the
jack PHONES.
ColibriDDC receiver, as all the range of Expert
Electronics equip ent with the direct signal sa pling
is designed so that the FPGA and icro controller
fir ware can be updated in the auto atic ode by
ExpertSDR2 progra without the direct involving of
User. Fir ware installation progra is fir ly
hardwired into the receiver's hardware. It allows to
fir ware the receiver without concerns over the
power failure. If there appear proble s with PC or
electricity, renewing of the fir ware can be
continued after the PC reboot or power recovery.
