General Information
Introduction
The Tunable AntennafierTM is a bidirectional amplifier with integrated narrow band high Q filtering
which is capable of being electronically tuned over an existing RF coax. Parameters such as center
frequency, TX power output, and RX gain can be remotely adjusted by the user with ease. Also,
status information such as center frequency lock detect, high RF input level, Temperature and
Amplifier personality information can be easily monitored.
Remotely tuning your AntennafierTM requires a Tunable Controller and either an Ethernet or USB
connection. Manually tuning of center frequency is also possible with a recessed push button switch
on the Tunable Controller faceplate.

Chapter 1 Getting Started
How it Tunes:
Controlling and reading your AntennafierTM parameters is easily accomplished with a Tunable Controller.
This device works together with your Tunable AntennafierTM to send and receive tuning and status
information via the 50 Ohm coax cable
connecting these devices. A typical setup is as shown below:
The Tunable Controller performs several operations. First it injects DC and 2.4GHz radio traffic onto the 50
Ohm Coax to feed the Bi-Directional Amplifier (AntennafierTM). Secondly it is an interface which controls
the Antennafier’sTM status and tune information via an Ethernet or USB connection.
The information exchanged between the Tunable Controller and AntennafierTM is also carried through the
50 Ohm coax and does not interfere with the 2.4GHz radio traffic.
When +12VDC is applied to the Tunable Controller a Built In Test (BIT) is initiated. During BIT the
Controller pulls vital status information from the AntennafiersTM built in memory. After passing BIT one can
easily change the Antennafier’sTM Channel with a recessed “SET” switch located on the Tunable
Controllers front panel or electronically change all parameters via the USB or Ethernet connection. Once
new information has been sent to the AntennafierTM it stores this in its internal memory.
The AntennafierTM always remembers its last tune information even when power is cycled. This is important
since the AntennafierTM can be used as a stand-alone device without a Tunable Controller. Just like our
standard non tunable amplifiers, this device can be operated in the same fashion.

2400DE Indoor Kit:
This kit is intended for indoor applications where the AntennafierTM is pre-tuned to customer
parameters and/or is placed inside or near the radio/antenna.
DC Power is applied to the unit via a 2.1mm jack located on AntennafierTM side.

* Tuning your indoor AntennafierTM requires a Tunable Controller (sold separately).
One Tunable Controller can do it all:
With one Tunable Controller alignment and monitoring can be performed on any Tunable
AntennafierTM. Once tuned parameters are sent to the amplifier the Controller can be removed if
desired. The AntennafierTM will remember its last tune information, even when power is cycled.
In the case of the Outdoor Model a basic DC Feed can be inserted. Likewise, in the case of indoor
setup the Tunable AntennafierTM receives its DC power via a 2.1mm jack located on the unit side.

Tunable AntennafierTM Applications:
The Tunable AntennafierTM is suited for applications where multiple co-located WLAN systems are located
and filtering of unwanted channel interference is desired. It accomplishes this by placing a tunable- high Q,
22 MHz Band Pass Filter around one of 14 user selectable channels. It also has user adjustable RX gain
and TX power output as well as status information such as BIT and Temp.
This product also automatically compensates for RF Coax losses induced in typical installation scenarios.
Many applications require the radio to be separated from the Transmitting Antenna, thus the need for an
AntennafierTM. The AntennafierTM is bi-directional and senses the incoming RF signal to determine either RX
or TX mode of operation. Receive is the default mode and Transmit is initiated once the input level
becomes greater than +2dBm. In transmit, the Power Output is held constant via AGC to the programmed
value even over an input range of +2 to +20dBm.
The Tunable AntennafierTM is intended for IEEE 802.11b WLAN radio systems operating in the 2.4 to 2.485
GHz. These systems are Half Duplex in nature and require fast turn-around times. The RF sensing circuits
and AGC are quick to lock and switch between TX and RX within typically 3 µSec or less.

Chapter 2 Hardware Installation
How to connect your AntennafierTM:
AntennafierTM connection can be accomplished in many ways. We suggest keeping the RF Coax Loss
between your AntennafierTM and Antenna to a minimum for maximum RF performance. This will maintain a
low System Noise Figure and ensure Maximum Output Power.

The DC power jack on the Tunable AntennafierTM is not needed since it receives power and tune info
via the controller.
