Enthusiasm for Ham radio is one of the foundations that led to the formation of Hilberling GmbH.
The know-how gained through years of experience in the development and series production of industrial and maritime high-frequency products flows directly into very special products for Ham radio.
Cutting-edge technology developed and manufactured in Germany!
2 Independent Receivers
7 x 1 GHz DDS oscillators are used for two equivalent receivers and a transmitter. This offers the highest spectral purity for receiving and transmitting with the PT‑8000A.
Extreme Frequency Stability
A low-noise SAW-VCXO at 640 MHz is disciplined by a 10 MHz quartz oven. The use of 1 GHz DDS oscillators enables the lowest noise figures, which can otherwise only be achieved with non-variable crystal oscillators.
Excellent Signal-to-Noise Ratio and very good RX / TX Intermodulation Behavior
A signal-to-noise ratio of -160 dBc / Hz at a 10 kHz distance at the RX frequency of 14.2 MHz is achieved. The frequency stability through the quartz oven is 5 x 10-9.
VHF Band Pass Filter
An automatically tuned preselector ensures preselection in the frequency range from 1.8 MHz to 30 MHz.
Power Output Amplifier
The 200 W transmitter output stage (PT8‑PA200) with 50 V UHF FETs used in the PT-8000A, which operates continuously from 1.8 MHz to 148 MHz is new in Ham radio.
Diplexer / Harmonic Filter
In the PT‑8000A, 7 diplexers / harmonic filters are used in the TX output for the first time in Ham radio technology. They prevent the harmonics from being reflected on filters and antennas.
