The development and production of a frequency spectrum receiver system and an antenna spectrum radar receiver system was his next brainchild. These equipments were able to monitor a frequency range up to 300MHz, as well as pin-point the direction of interference transmitters. In the year 1958, this became an absolute necessity as the use of frequency ranges increased drastically.

When TV2 in Germany started broadcasting, the German Federal Post extended the UHF broadcasting network and relied on Plisch to develop the first Frequency Converter from ZF to UHF. This development in 1964 gave birth to the first range of tunable coaxial cavity resonator with a gold plated surface, which eliminates the need for maintenance.

Sales of TV frequency converters and interference measurement equipment increased by the Year 1966 and with increasing sales volume, Plisch reinvested their huge profits into R&D and in 1968 developed a frequency converter with a capacity of 1kW.

This Coaxial Cavity Resonator Technology was the base of all High Powered Transmitters with 10kW and 20kW capacity you see today. In 1969 when Solid State Technology was introduced the development of VHF/ UHF transponders ranging from 1 Watt to 20 Watt was put in place.

This followed with the development of 2.5 and 10kW transmitters, which transpired during the years 1970 to 1975 when Plisch introduced the linearity pre-correctors to greatly improve the “radius of activity”.

While others were looking at the advancement of Plisch as leaders in Transmitter Technology, Plisch once again surprised the world with the introduction of the “Jolly B” – the first transposer using modular architecture. The Industry in 1978 saw this Modular Technology as a Miracle to Service Engineers. Faulty modules were simply exchangeable without costly repairs or site maintenance.

Plisch’s Tube power amplifiers up to 20kW with maintenance free coaxial cavity resonator were also marketed & sold worldwide by Rohde & Schwarz, then a new comer to the Transmission scene.

Plisch concentrated further in Research and Development and was responsible for the first hypervapotron cooling system. At this stage Annual Sales of 10Kw transponders reached 1000 pcs Per Year.

During the 90’s Plisch’s number of employees grew to 250 with a turnover of more than DM 25,000,000 per year.

With new and more effective cooling methods being developed, together with changes from bipolar transistors to LDMOS Technology, European Broadcasters bought up more than 150 DAB Transmitters and 50 DVB Transmitters quickly during the end of the Nineties.

From 2000 onwards the Plisch product range was completely revised and a complete modular system ranging from 1 Watt to 80kW using state of the art LDMOS technology and the latest remote control systems (SNMP, Bit Bus, R232, modem and serial ports ) was developed for both analog and digital in VHF and UHF.

Plisch decided to expand its frontiers internationally and increased its revenues by 30%. This made way for a second generation of digital TV systems – DAB & DVT – T. Automatic Linearity Pre-Correctors and Management Systems completed the Plisch product range.

Plisch, with the Plug-in Technology could transform its transmitters from Analog to DVB-T and DAB by just a simple switch command. This allowed a TV Channel to Transmit in analog during the day and switch to digital for Test Trials in the night or even use it as a DAB Transmitter.

This was branded as THE BRILLIANCE OF PLISCH TECHNOLOGY.

To expand further into the world market Plisch in 2003 set up an office in Kuala Lumpur Malaysia – Plisch Broadcast Asia Pacific Sdn Bhd, This office will market and support Plisch products in the Asian Region and provide after-sales service with a complete inventory of spare parts to be readily available for all its distributors in Asia.

Revenue is expected to increase around 35% in the Asian market.

Today, Plisch is not only an Industry Leader but also an International Company with a solid financial foundation, still exploring the frontier for state-of-the-art transmission technology with products and services beyond any comparison.
