Rev. 2.0
Page 1 of 2
DESCRIPTION:
Super regenerative ASK receiver manufactured
in SMT technology on printed circuit.
Cascoded input stage improves separation between
antenna and oscillator-detector; the receive frequency
tuning is achieved through a lowered variable coil.
HIGHLIGHTS:
Developed according to I-ETS 300 220 e ETS 300 683
European Standard.
APPLICATIONS:
Anti-theft systems, door openers,
security systems, data transmission and more.
