Product Code: RTC25
 |
The RTC 25 Transmitter Combiner is very compact and, in spite of
its small size, it features very good characteristics. Its
inherent intermodulation generation is kept extremely low, using
Wisycom transmitters, thanks to the very high-quality ?-3 dB
power-coupler module? and other devices employed, accurately
selected between the top-class brands on the market.
Furthermore, a very low-loss and sharp low-pass filter on the
output prevents any harmonics. Also the cross-talk between the
inputs is very low, since they are decoupled by circulators. The
RTC 25 allows to operate also with output mismatching: in case
of bad antenna or cable-impedance characteristics, the
reflected-power coming back from the antenna is redirected to
its internal dummy-load, capable to absorb a continuous power of
up to 100 W. The Transmitter-Combiner output-power can be
monitored on the front-panel RF-meter featuring two scales, for
the precise reading of one-signal and two-signal working. The
RTC 25 features also an accurate SWR-overflow surveillance
circuit: the red LED light-on when the antenna SWR goes in
excess of 1 : 2. In the back-panel is located the feeding
connector; the internal relevant fuse is a self-resetting type.
