Combilent Group develops and delivers state of the art
RF Critical Communication Infrastructure Products
Combilent Transmitter Combiners are designed to facilitate site optimization and maintenance. They include remote and continuous configuring, features for monitoring and controlling antenna RF power (forward and reflected), antenna return loss (VSWR) and more.
DS18818 – Cavity Combiner
Combilent provide a line of compact cavity combiners featuring integrated antenna power monitoring. Models are available covering UHF 350-512 MHz and 700/800/900 MHz bands.
Alarms are generated upon high antenna VSWR and/or high temperature and are user configured through Ethernet or SNMP.
Ethernet, web interface SNMP, and SYSLOG enabled monitors provide information on forward power, reflected power, antenna VSWR and heat sink temperature while also allowing for easy factory or field tuning using only the base station radio and a PC.
All modules are broad band (20 MHz) and symmetrical.

DS18825 – Tx Filter
Integrated milled one-block Tx filter units with compact dimensions and high levels of integration.
Less potential for loss, failure and intermodulation due to Combilent design innovations that incorporate less cables, components and connections.
Combilent filters feature optimized insertion loss, attenuation, bandwidth and selectivity to ensure ideal system performance.

DS21955 – Duplexer capabilities
Duplexers range in size and power handling capability, from two channel units to multi-channel high-power base station units, providing critical isolation between receiver and transmitter.
No tuning required (tuned to customer frequencies at our factory)

DS15543 – TMA
Combilent’s TMA/TTA products offer the most and lightweight and compact form factor on the market for ease of installation and integration.
Quality manufactured, integrated one-block unit, ensuring less points of failure and lower noise figure from less cables, components and connectors.
Integrated filter (band pass or duplexer) and LNA with onboard surge protection.
System gain setting, visual indicators and relay alarm output at the Receive Multi-Coupler (RMC).
Rx distribution from the RMC (AC mains or DC power supplied).
Combilent TMAs are 50% more compact than industry-standard TMAs.
DS18855 – RMC
Combilent’s High Performance RMCs include high selectivity band-pass pre-selectors for protection against unwanted noise, as well as balanced amplification and an integrated DC back-up connection (+12V).
Designed for VHF, UHF and 700/800/900 MHz.
Gain control and status are visible on the front panel display.
The RMC parts are housed in a single chassis for rack-mounting in Base Transceiver Stations. Cable
runs and cabling costs are minimized, and cable signal loss and noise figures are reduced.Ethernet, web interface SNMP and syslog enable monitoring of system health and configuration of
system gain.Single band and dual band RMC versions are available (no TMA).

DS21736 – Tx Composite Power Monitor
Functions on one or two channels.
Measures the total RMS power of all signals in the system using a dual directional coupler, a switch selecting forward or reflected power and an RMS detector.
Ethernet / web-server SNMP enabled / SYSLOG.

DS19788 – Tx Stand alone Frequency Selective Power Monitor
Frequency selective.
Supports up to 10 carriers of 50W each.
Passive intermodulation hardened.
Compact form factor, 2RU.
Ethernet / web-server SNMP / SYSLOG enabled.
Measures forward and reflected power, antenna VSWR and temperature.
Alarms are user configured via web interface or SNMP.

DS21093 – Rx VSWR Monitor
The RX Antenna VSWR Monitor attaches between the RMC and the RX antenna.
VSWR of the receiver antenna is monitored periodically, with data accessed through
Ethernet, web server and SNMP.The RX signal runs through the RX Antenna VSWR Monitor. It has low insertion loss
and maintains signal integrity.Picture shows an in-line Rx VSWR Antenna Monitor with ETH interface, integrated web-server, SNMP, and relay alarm output
