Product overview

Triple Band (AWS/PCS/WCS) Twin TMA with 700/850 Bypass
Each TMA has independent gain control of 6 to 12dB
Fail-safe bypass mode and multi-strike lightning protection
Small lightweight unit offers high reliability of >500K Hours MTBF
Highly linear amplifier with low intermodulation

 

CCI’s Triple Band (AWS/PCS/WCS) Twin TMA with 700/850 bypass contains
two triple band TMA’s in a single housing. Each TMA in the housing is fully
duplexed and shares a singles LNA for all three bands. The bypass path
provides excellent isolation to the TMA path. Separate antenna ports for the
bypass path and TMA path are combined onto a single BTS port. The Twin
TMA's low noise, highly linear amplifiers improve the uplink sensitivity and the
receive performance of the base station. The TMA is fully compliant with the
AISG 2.0 specification and supports CDMA, EDGE/GSM, UMTS and LTE BTS
equipment. The unit is ideally suited for sites upgraded to quad-band using
the existing infrastructure. The TMA allows the sharing of feeder lines for all
bands thus reducing tower loading, leasing, and installation costs. The input
and output connectors are located inline for ease of installation in space
constrained areas such as uni-pole structures and stealth antennas.
Technical Description:
The TMA system is an outdoor triple band twin tower mount unit which
provides low noise amplification of PCS, AWS, and WCS uplink signals
combined with 700/850 bypassed signals from separate antenna ports to a
common BTS port. The tower mount unit consists of 14 band-pass filters,
two redundant low noise amplifiers (LNA) with bypass failure circuitry, two
bias tees, AISG control circuitry, and lightning protection circuitry all housed
in an IP68 enclosure suited to long life masthead mounting. The AWS, PCS
and WCS paths are dual duplexed to separate the low power uplink signals
from the high power down link signals at the BTS and antenna ports. The
AWS, PCS, and WCS uplink signals are amplified with a dedicated ultra-low
noise PHEMT LNA with adjustable gain control. The unit provides protection
against lightning strikes via a multistage surge protection circuit. DC power
and AISG 2.0 control is provided via the BTS feeder cable. The unit operates
in current window alarm (CWA) mode until a valid AISG message is detected,
at which point it automatically switches to AISG mode. Once in AISG mode,
the unit can only switch back to CWA mode with the receipt of an AISG CCI
vendor defined command. In CWA mode, the unit requires 12VDC at each
BTS port and follows typical current window convention. In AISG mode, the
unit will accept 10-30 VDC from either BTS port. In AISG mode, the unit does
not require an AISG 2.0 compatible site control unit (SCU) and may also be
powered by a standard power distribution unit (PDU).

An optional Site Control Unit (SCU) is available to power up to 32 AISG
modules per sector and to provide the monitoring and alarm functions for
the system. The SCU is housed in a single (1U) 1.75” x 19” rack and contains
dual redundant power supplies capable of being “hot swapped” that provide a
regulated DC supply voltage on the RF coax for the tower mount amplifiers.
