for installation by FCC LICENSEES and QUALIFIED INSTALLERS. You MUST have an FCC
LICENSE or express consent of an FCC Licensee to operate this device. You MUST register
Class B signal boosters (as defined in 47 CFR 90.219) online at www.fcc.gov/signal-
boosters/registration. Unauthorized use may result in significant forfeiture penalties, including
penalties in excess of $100,000 for each continuing violation. The installation procedure must
result in the signal booster complying with FCC requirements 90.219(d). In order to meet FCC
requirements 90.219(d), it may be necessary for the installer to reduce the UL and/or DL output
power for certain installations.
ATTENTION: This device complies with Part 15 of the FCC rules. Operation is subject
to the following two conditions: (1) this device may not cause harmful interference and
(2) this device must accept any interference received, including interference that may
cause undesired operation.
ATTENTION: FCC regulation mandate that the ERP of type B signal boosters should
not exceed 5W. This Signal Booster has a composite output power of 1W, therefore
the gain of the DL antenna should be of 6dBi or less and maintain a minimum
separation of 25 cm from all persons, and the gain of the UL antenna should be 13dBi
or less and maintain a minimum separation of 28cm from all persons.
IC Compliance
As per RSS 131 Issue 2:
Nominal passband gain: 80dB max
Nominal bandwidth: 8MHz maximum for Canada market
Rated mean output power: Up to +30dBm
Input and Output imedances: 50 ohms
The Manufacturer's rated output power of this equipment is for single carrier operation. For
situations when multiple carrier signals are present, the rating would have to be reduced by 3.5
dB, especially where the output signal is re-radiated and can cause interference to adjacent band
users. This power reduction is to be by means of input power or gain reduction and not by an
attenuator at the output of the device.
RF Exposure Statement for ISED: “This device complies with Health Canada’s Safety Code. The
installer of this device shouldensure that RF radiation is not emitted in excess of the Health
Canada’s requirement. Information can be obtained at http://www.hc-sc.gc.ca/ewh-

2. Product Description.
The H7 Series Compact Signal Booster are IF SAW based Adjustable Bandwidth signal boosters that operates
in the downlink frequency of 763-775MHz and in the uplink frequency of 793-805MHz for United States. For
Canada it operates in the downlink frequency of 768-776MHz and in the uplink frequency of 798-806MHz.
This Signal boosters extends the radio coverage into areas inside the Base Station range where propagation
losses prevent reliable communication.
The system receives the UL signal though a Donor antenna to be amplified, filtered and re-radiated through
the Service antennas. The DL signal is received by the Service antennas to be amplified, filtered and re-
radiated through the Donor antenna back to the Base Station. This way, the system works as a Bidirectional
Amplifier.
This signal booster is capable of handling one Adjustable Bandwidth band from 700KHz to 12Mhz in uplink
and downlink. The start and stop frequency can be tuned via a software interface.
The intermediate filtering of this equipment is performed using IF SAW filtering technology and, among many,
it has the following features:
- High Selectivity.
- Adjustable BW filter.
- Uplink Squelch with configurable threshold and configurable time hysteresis.
This Digital Signal Booster has a compact heavy duty IP67/NEMA4X cabinet for outdoor usage, it is designed
to be wall or pole mounted.

3. Signal Booster Block Diagram
This Signal Booster is basically a bi-directional amplifier, the downlink signals are received by the Signal
Booster from cell site by the donor antenna, filtered by its internal duplexers and IF filters units, amplified by
low noise amplifier(LNA) and downlink PA unit, and then sent via the server antenna to the area to improve
mobile signals for mobile phones.
The uplink signal of mobile devices from the coverage area is input via the server antenna, then filtered by
duplexers and IF filters units, amplified by the uplink low noise amplifier (LNA) and the uplink PA unit and
finally sent via the donor antenna to the cell site tower.
A detector in the PA stage measures continuously the output level. The signals from this detector is used
by the automatic gain control(AGC), to supervise and, if necessary, reduce the chain gain, in order to keep
the output power level, under the maximum.
All the parameters are supervised by a microcontroller.
4. Installation
Mounting the Signal Booster
The Fiplex Compact Signal Booster is designed for outdoor usage with a weather proof outdoor cabinet
that can be mounted without any kind of shelter from rain, snow or hail.
However, to improve reliability, it is recommended to mount the Signal Booster on a site with some kind of
shelter from direct exposure to sun, rain, snow and hailing.
We extremely recommend not operating the Signal Booster under very bad weather conditions, such as:
- Intense rainfall, snowfall or hail
- Storm or high wind
- Extremely low or high temperature
- High humidity of the air

Starting operation
1. Setup desired filter configuration using pFOMS (only for programmable band selective and
programmable channel selective models).
For fixed bandwidth Signal Boosters this feature will not allow user to make changes, so, skip this step for
fixed bandwidth models.
2. Setup desired operating gain using pFOMS. UL and DL chain are independent, so both values must be
set.
For nominal gain of the Signal Booster these values must be set to zero.
Figure 7
Figure 7 shows how to set up manual attenuation values.
UM-0825 19
Auto-oscillation Condition
If the isolation between donor and service antennas system is lower than required, the amplified signal will
go back from service antenna to donor antenna. It will lead to self-oscillation, reducing the coverage area
and amplified signal quality.
The isolation between donor and service antennas systems must be, the nominal Signal Booster gain plus
15dB, in order to assure the properly operation of the Signal Booster.
.
Status Indicators
There is an indicator panel located at the front panel of the Signal Booster. This led panel works as a status
monitor, in order to advice different operational conditions of the Signal Booster.
There are four leds, first one the power ON indication led, labelled “PWR”.
A Second led, labelled “STS” resumes warnings regarding critical operational conditions of the Signal
Booster.
Third and fourth led resumes operational conditions for uplink “UL” and downlink “DL” chains.
Signalling will be explained in table 1.

Table 1
1. Start UP
Every time the Signal Booster is plugged to AC mains (or auxiliary DC power), will start a self diagnosis and
booting sequence that lasts around 20 seconds, during this time Signal Booster is not available for traffic,
and the reason is because an automatic antenna isolation control procedure runs in order to detect poor
isolation conditions. During this time all leds in the front panel will blink.
In case of bad isolation condition led “UL” or “DL” (depends on the path where auto-oscillation condition
was detected) will stay ON during five seconds.
2. Stationary state
Once the booting sequence is finished and under no AGC or Overload conditions only the PWR led must
keep ON.
3. AGC DL
Blinking condition indicates that AGC circuitry is active for downlink path. For further information
please read Automatic Gain Control (AGC) latter in this chapter.
4. AGC UL
Blinking condition indicates that AGC circuitry is active for uplink path. For further information
please read Automatic Gain Control (AGC) latter in this chapter.
5. Overload DL
Led permanently ON indicates that Overload protection circuitry for downlink path is active.
For further information please read Overload Protection latter in this chapter.
6. Overload UL
Led permanently ON indicates that Overload protection circuitry for uplink path is active.
For further information please read Overload Protection latter in this chapter.
Automatic Gain Control (AGC)
Automatic Gain Control circuitry is intended to keep Signal Booster’s output power at a fixed level when input
signals exceed maximum values, avoiding quality signal degradation by intermodulation generation.
When AGC is active AGC leds from UL or DL (or both) will blink, this means that signal level from donor site
(or from service area) plus Signal Booster gain produces an output power that is above the maximum
composite output power of the Signal Booster. This should not be considered an undesired working condition,
UM-0825 21
far from that; this is the best operating condition because you are getting the maximum composite output
power available from the Signal Booster.
Anyway is a good practice to increase attenuation (reducing gain), until AGC led turns off, this operation
releases AGC circuitry dynamic range.
Also is a good practice to check signals from donor site to ensure that undesired signals are not being
amplified by the Signal Booster, or even desired signal levels are not excessively high taking Signal
Booster to an overload condition.
Overload Protection
When AGC circuit reaches its limit, the power amplifier stage is shut down to prevent harmful distortion and
potential damage to the Signal Booster. After approximately ten seconds the system checks if overload
condition is still present, if this happens amplifiers will remain off. This cyclic check will continue until condition
that makes AGC circuitry reach its limits disappears.
Conditions that can cause AGC to reach its limits include the presence of one or more very strong channels,
a strong in-band noise source, or amplifier oscillation due to poor antenna isolation.
When overload protection lower row led from UL or DL (or both) will be ON permanently.
Laboratory Measurements
For specific parameters verification and laboratory tests, please contact factory.
Detailed procedures, recommended tests set up, and a knowledge engineering team will bring adequate
support to perform this measurements in a comfortable and safely way.
