MTS Frequency

Duplex Spacing
transmitter frequency being
higher.
800 MHz
19 MHz
Duplex spacing between a
transmitter frequency and the
corresponding receive fre-
quency is 45 MHz.
900 MHz
5 MHz
Duplex spacing between a
transmitter frequency and the
corresponding receive fre-
quency is 15 MHz.
1.7.1.3
Post Filter
A Post Filter consist of one bandpass filter which allows the transmitter signal to pass. The Post Filter
supports non-duplexed configurations and incorporates a Digital Power Meter (DPM).
A Post Filter is only available for the MTS 4 as MTS LiTE and MTS 2 do not support non-duplexed
configurations.
1.7.1.4
Cavity Combiners
A Cavity Combiner combines RF signal from a number of different base radios into one transmitter
filter.
The following Cavity Combiner (CC) are available:
• Auto Tune Cavity Combiners (ATCC)
• Manual Tune Cavity Combiners (MTCC)
MTCCs are functionally the same as ATCCs except that they are tuned manually instead of
electronically.
NOTICE: 260 MHz configurations do not support MTCC.
MTS LiTE and MTS 2 do not support Cavity Combiners.
Minimum channel spacing of the TX channels is 150 kHz while the recommended channel spacing is
250 kHz. This limitation applies to all Cavity Combiners in all cabinets connected to the same transmit
antenna.
1.7.1.5
Hybrid Combiner
A Hybrid Combiner combines RF signal from a number of different base radios into one transmitter
filter.
The Hybrid Combiner (HC) combines up to two transmitters.
The combiner has no limitations in respect to channel spacing of the TX channels. However, for
frequency planning and interference reasons, at least 50 kHz is recommended.
NOTICE: MTS LiTE does not support Hybrid Combiners.
