1. ADRF-25K
1.1 Introduction
Dual bands in one body: ADRF-25K is an over-the-air repeater system that
operates in both the Cellular (824 - 894 MHz) and PCS (1850 – 1990 MHz)
frequencies. It has one input and one output port.
1.1.1 Highlights
• Dual band Repeater
• Covers the 60 MHz PCS band
• Covers the 25MHz Cellular band [A Band or B Band]
• Three switchable SAW filters: You can select any contiguous 5, 10, or 15
MHz bandwidth anywhere within the full 60MHz PCS spectrum.
•. Total out-of-the-box solution: ADRF-25K has all the necessary parts that you
need.The system includes dual band repeater, donor antennas, server antennas,
cables and accessories.
• EVDO Rev. A: ADRF-25K is fully compatible with EVDO Rev. A
• Ec/Io: In order to ensure proper system installation, in addition to the RSSI
indicator on the ADRF-25K’s front panel, you can also read Ec/Io values via
the user interface program.
• Incremental Automatic Shutdown/Resumption Time: ADRF-25K gradually
increases the time span between automatic shutdown and resumption before it
permanently shuts itself down
• AI compatible: ADRF-25K is fully compatible with Applied Innovation’s
monitoring system.
• Versatility and Usability: ADRF-25K gives total control to the user. Most of
the control parameters, e.g., gain, output power, alarm threshold, etc. can be
changed using the user interface so that the user can adjust the system
perfectly to the given RF environment. At the same time, due to its intuitive
user interface, the user won’t even need to read the manual to get a grip of the
system.
• 81 ± 2 dB gain @ PCS, 72 ± 2 dB gain @ Cellular
• 30 dB AGC Range @ 0.5 dB Step
• Sharp out-of-band rejection; 50 dBc @ ±1.5 MHz from the Cellular Sub-band
edge , 50 dBc @ ±1 MHz from the PCS Sub-band edge
• Supports DHCP; No 3rd party GUI software required
• Automated installation

2.3 Installation
2.3.1 Tools
No special tools or equipment are needed to install the ADRF-25K.
2.3.2 Procedure
Four mounting holes are located on the wall-mounting bracket to attach it to the
wall. The wall bracket must be securely attached to sufficiently carry the weight
of the ADRF-25K, which is bolted to the wall bracket through the four aligned
mounting holes.
The following steps should be followed while mounting the repeater:
Installation Procedure
① Verify that the Repeater and Mounting Bracket are in good condition.
② Drill holes in the installation surface and insert the anchor bolts.
③ Set the mounting bracket against the wall.
④ Using the Hooks on top, set the Repeater against the mounting bracket.
⑤ Using the anchor bolts attach the Repeater to the Bracket.
⑥ Make sure the Repeater is securely attached.
⑦ Connect the GND cable.
⑧ Connect the Antenna cable.
⑨ Connect the Power.
⑩ Using a laptop, install the Repeater.

2.3.3 Grounding

Verizon Wireless MPE25K RF Repeater
User Manual V0.3
Advanced RF Technologies, Inc. Proprietary Document 19/59
2.3.4 Antenna Separation/Isolation
Separation between the antennas is necessary to prevent oscillation. Oscillation
occurs when the signal entering the system continually reenters, due to the lack
of separation between the donor and server antennas. In other words, the signal
is being fed back into the system. This creates a constant amplification of the
same signal. As a result, the noise level rises above the signal level.
To prevent feedback, the donor and server antennas must be separated by an
appropriate distance to provide sufficient isolation. Isolation is attained by
separating antennas a sufficient distance so that the output of one antenna does
not reach the input of the other. This distance is dependent on the gain of the
repeater.
A sufficient isolation value is 13 ~ 15 dB greater than the maximum gain of the
repeater. For example, if the gain of the repeater is 50 dB, then an isolation of
63 ~ 65 dB or greater is required. In the same manner, because the ADRF-25K
has a maximum gain of 80 dB, it requires an isolation of at least 93 ~ 95 dB.

Verizon Wireless MPE25K RF Repeater
User Manual V0.3
Advanced RF Technologies, Inc. Proprietary Document 20/59
2.3.5 Line of Sight
The donor antenna which points towards the base station typically has a narrow
beam antenna pattern. As a result, a slight deviation away from the direction of
the BTS can lead to less than optimum results. In addition, obstacles between
the repeater and the BTS may impair the repeater from obtaining any BTS
signal. As a result, the repeater cannot transmit signal to the coverage area.
Therefore, a direct line of sight to the BTS for the donor antenna is vital to the
function of a repeater. For the same reason, placing the server antenna in
direct line of sight of the coverage area is also necessary.

4. Maintenance Guide for ADRF-25K
4.1 Periodic Inspection Checklist
a. Check for loose connections between the repeater and antennas. If
connections are loose, make sure that all connections are tightly fastened
properly.
b. Cables and connectors are in good condition.
c. Ensure that the repeater brackets are in good condition and that the repeater is
securely fastened.
4.2 Preventive Measures for Optimal Operation
4.2.1 Recommendations
• Perform the Periodic Inspection Checklist quarterly or semiannually.
4.2.2 Precautions
• Do not operate the repeater with the antennas in extremely close proximity to
one another as this may cause damage to the repeater.
• Do not change the parameters unless instructed to do so by an authorized
supervisor.
• Do not move the repeater unless instructed to do so by an authorized
supervisor.
• Do not detach any cables to the repeater unless repair of respective
components is necessary.

Power Supply
It provides DC power to each module within the repeater.
Controller
It is responsible for monitoring the status of each module and controls the
parameters.
PCS Up / Down Converter Module
The downlink RF signal that enters through the cavity filter is converted to IF
frequency, which is later converted back to RF frequency through SAW filtering.
Cellular Up / Down Converter Module
The downlink RF signal that enters through the cavity filter is converted to IF
frequency, which is later converted back to RF frequency through SAW filtering.
PCS Duplexer
It consists of two BPFs (band-pass filters): PCS TX (1930 ~ 1990 MHz) & RX
(1850 ~ 1910 MHz)
Triplexer
Combines Cellular and PCS signals. It consists of three BPFs (band-pass filters):
PCS and Cellular TX and RX.
Modem Module
Contains the CDMA 2000 modem (Kyocera M200).
