Description
In 1981, I was invited by TELEPATCH to develop a digital frequency synthesizer that would be the basis for all of TELEPATCH's new transceivers.
After almost a year of work, in 1982, the first Brazilian multi-channel synthesized UHF/VHF transceiver was born using digital PLL for frequency generation instead of crystals.
Most Brazilian public services, such as military police, federal police, firefighters, etc., successfully used TELEPATCH transceivers.
In addition to mobile transceivers, TELEPATCH had also manufactured portable transceivers, repeaters, power supplies, car radio-telephones, and many other communication products.
