DESCRIPTION
Narda medium and high power cellular band power
combiner/dividers are capable of distributing medium
and high power Tx signals without tuning constraints or
size constraints. Most significantly, these devices can
withstand full-rated power even if the output circuit is
opened or short circuited. Consequently, these models
are ideal for antenna feed circuits. Other models are
available for other cellular bands.
Isolation is typically in the 25 dB range and return loss is
typically in the 20 dB range. Insertion loss, exclusive of
signal combination loss, is less than 0.5 dB.
Special versions offer high isolation with 40 dB and 60 dB
versions available on special request. These units make
use of Narda’ single-junction and dual-junction isolators.
Hybrid Combiner Networks are also available to custom
specifications (see page 34). High power 200 W or 500 W
hybrids are provided in a 19
12
” rack assembly complete
with cabling and terminations (isolators can also be
provided), to combine two through six channels of high
power level Tx signals.
Contact Narda’s regional sales engineers for details on
these high-performance products.

There is no combined loss when input frequencies are equal and in phase.
** Case Temperature must be limited to 85°C maximum, cooling fan may be required
