2. The System
The system consists of a Tx part and an Rx part. Each of the parts is comprised of a
box, a 5V 2A DC power supply and 3 main board components:
 A wireless board, that contains the antennas, the RF components and the
Baseband (BB) chip. The wireless board is:
o Shaldag – Third generation board, based on Amimon 2
st
generation
BB and Amimon single-chip RFIC
 An interface (also called ‘application’ or ‘I/O’) board which is the audio-video
input/output board. The interface board is called Seagull, and is numbered
AMN_PCB_117/118
 A User-Interface board that has LEDs and buttons. (AMN60)
Note
: The functionality and operation described in this document is identical to all
three possible wireless boards, unless specifically noted
2.1 Tx side
2.1.1 Wireless Tx board
The Shaldag wireless Tx board is the transmission part of AMIMON's wireless
system. The board has 5 printed antennas, 4 of which are for transmission and 1 is
for reception of the back-channel. In addition there is one uplink reception diversity
antenna. The board also contains the RF components, the Baseband Tx chip and the
MAC microprocessor. On the Shaldag board the MAC microprocessor is embedded
inside the BB chip. It is connected to the Seagull interface board through a WHDI
connector. The wireless board receives its power supply from the Seagull interface
board through the WHDI connector.
2.1.2 Seagull Interface Tx Board
The Seagull Interface Tx board is used to connect from the various sources to the
wireless link. It contains the following video and audio inputs:
 2 HDMI inputs
 VGA input (optional)
 Stereo I
2
S audio (optional)
 Optical SPDIF audio input (optional)
Seagull board supports the following Amimon’s wireless module (see fig 1.a):
