for single band models and either a 2 Watt or 10 Watt downlink output level @ 1 db compression for dual band models. Table 1 lists all of the models available as well as their uplink / downlink passbands and downlink output power. OVERVIEW Signal Boosters extend radio coverage into areas where abrupt RF propagation losses prevent reliable communication. No frequency translation (conversion) occurs with this device.

/ Downlink In” must be connected to the antenna pointing towards the base station. The RF connection labeled “Uplink In / Downlink Out” must be connected to the antenna facing the area to be covered by the signal booster. RF connections must be made through cables with characteristic impedance of 50 ohms. Isolation between the two antennas should be at least 15 dB higher than the signal booster gain. Isolation less than this value can cause gain ripple across the band.

The signal booster uses external heat sinks and needs to be mounted such that there can be unobstructed air flow over the heat sink fins.
MEASUREMENT PROCEDURE To measure the antenna isolation perform the following in a step-by-step fashion. sary to insure that no conditions exist that could possibly damage the signal booster and should not be skipped for even the most thoroughly designed system. 1) Set the signal generator for a 0 dBm output level at the center frequency of one of the boosters passbands.
should exceed the signal booster’s gain figure by at least 15 dB. 5) Repeat step 4 again with the signal generator set to frequencies at the passbands edges in order to see if the isolation is remaining relatively constant over the complete width of the passband. 6) Repeat the isolation measurements at the other system passbands to determine the overall minimum isolation value for the system. Physical modification of the antenna system maybe required in order to reach an acceptable minimum value.

CAUTION: Operation of the signal booster at maximum gain with greater than -20 dBm average power incident on either of the RF Input connectors can cause damage to the signal booster.
