siae oscilloscope 431a (introduced in 1963) used synthesizer in studio di fonologia musicale di radio milano



company s headquarters in cologno monzese, approx. 1966

a few years after founding siae, edoardo mascetti co-founded in 1958 microelettronica s.p.a., company business design of telecommunication equipment radio , landline systems , located in basement in milan. in 1963, 2 complementary companies merged siae microelettronica s.p.a. , headquarters moved nearby town of cologno monzese, larger area available accommodate new offices , manufacturing plant.

the new company counted less 50 employees , focused business on telecommunication systems, rising capillary diffusion of telephone systems in italy. analog multiplexing systems telephone providers constituted company s principal product; nonetheless, in 1963, company began active collaboration enel, italian provider of electric power, in order create supervision system national distribution network, successful outcome later fostered similar activities in northern europe , in norway.

by mid 60s, company began actively promoting products advertising in technical journals natural consequence of growing business, first large-scale commercialized radio transceiver: 3-channel 3-b3 , later rt450 (1966), capable of aggregating 48 channels uhf band. rt450 equipment certified it:telettra under commercial name h450 fallback link high-capacity solutions. power-line communication systems manufactured company in years along first fixed , mobile communication terminals in vhf band (1972) vehicular communications (precurring modern mobile phones) , anti burglar alarm systems.

2.3ghz modulator rt12 transceivers, exploiting microstrip technology on ptfe connections , electromagnetic coupling filtering , splitting purposes (1978).

by 1973, whole new internal division created design of television broadcasting equipments (repeaters , transmitters) main customer national television company rai. first television products based on thermo-ionic tubes though improvement of solid state technologies replaced vacuum tubes. similar improvements in printed board manufacturing made microstrip circuits viable solution increasingly-high microwave frequencies , in 1978 rt12 radio equipment boasted first direct-conversion 2.3 ghz synthesized modulator , aggregate 120 telephone channels. in these years, company manufactured historical link connect milan , rome branches of corriere della sera newspaper.

the employees hundred though company still remained family-run business lead founder , tight board of managers through 70s. computer-aided design of electronic circuits approached , exploited improve yield , reduce design time critical high-frequency sections.
