RPA 25 30W Power Amplifier (1/2 x 19”/2U standard-rack)

The RPA25 Power Amplifier is very compact and, in spite of its small size, it features appreciated and unique characteristics.

Its inherent noise is extremely low and thanks to the very sharp output low-pass filter, also the amplified noise eventually generated by the transmitter/exciter is kept to a minimum.

The RPA25 allows to operate also with output mismatching: in case of bad antenna or cable-impedance characteristics, the amplifier is not shut-off (as the most part of less-performing amplifiers) but instead the reflected-power coming from the antenna is redirected, by the built-in output-isolator, to its internal dummy-load. This prevents the overloading of the final power-stage and in this way even any intermodulation product and/or noise generation are avoided.

The amplifier output-power can be read in the front-panel meter and can be adjusted by the front-panel knob (PWR ADJ.). Pushing the red button (PUSH TO REFL), you can read on the meter the antenna reflected-power.

The RPA25 features accurate temperature measuring and surveillance.Four LED’s indicate: correct working (< 50 °C, ON), acceptable working temperature (+50 ÷ +55 °C, T NORM), high working temperature (+55 ÷ +60 °C, T HIGH), and over-heating (> +60 °C, PWR OFF).In this last case the amplifier is automatically shut-off (until it cools-off) to prevent scorching of the operator.

The apparatus can be powered by a wide range of DC powering-voltages, without reducing performances, thanks to the built-in very high-efficiency dc/dc power converter.

In the back-panel are located the feeding connector and the relevant fuse; in case the fuse breaks, the relevant LED in the front-panel (FUSE OFF) turns-on.

RTC 25 2 x 50W Transmitter-Combiner (1/2 x 19”/2U standard-rack)

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. Pushing the red button (PUSH TO REFL), you can read on the meter the antenna reflected-power.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.

TECHNICAL DATA• Frequency range : the RTC 25 can be supplied for one of the following ranges: ⇒ 300 ÷ 360 MHz (BW > 12 MHz) ⇒ 470 ÷ 880 MHz (BW > 25 MHz). others on request.• Input power max : 2 x 50 W continuous.• Output power : -4 dB referred to the total input power.• Spurious emissions : < -85 dBc (-90 dBc typ.).• In / Out impedance : 50 Ohm.• Input VSWR : < 1.2 : 1.• Output VSWR max : infinite, with 2 x 50 W continuous input power. • Power source : 10 ÷ 20 Vdc, negative ground.• Power consumption [@13V] : 50 mA max.• Size : 243 x 87 mm (1/2 x 19”/2U standard-rack) x 230 mm depth.• Weight : 4 kg approx.
