Tunable Filters - TMA/TMG Series
N
Tunable Multicouplers
K&L Microwave’s Tunable Multicouplers
enable up to four transceivers to
operate simultaneously in transmission
and reception mode using a common
antenna. Each multicoupler can be
arranged in either ground base or
airborne rack assemblies with up to
four individually packaged tunable
filters in each.
The filters within the tunable multicoupler
can cover either the VHF (100-160MHz)
or UHF (225-400MHz) communications
band. Each filter is available with 3
through 6 sections and a nominal 3dB
bandwidth ranging from 0.35 to 5%.
Control of each tunable filter is either
manually, through a front panel
dial assembly, or remotely, through a
digitally controlled option. For specifics
on the filter configurations, refer to the
BT series and the Digital Tunable
sections of this catalog.
