Abstract

<B>BLOQUEADOR/TRANSMISSOR DE SINAL DE RADIOTELEFONIA CELULAR<D>, compreendendo moduladores programáveis (M1), (M2) e (Mn) geradores de portadoras (F1), (F2) e (Fn) de diferentes freq³ências e diferentes modulações, cada qual correspondendo a um determinado sistema de comunicação convencional de radiotelefonia celular, de modo que tais freq³ências e modulações possam ser introduzidas em um somador (1), onde as portadoras de diferentes freq³ências são agrupadas em um mesmo cabo de saída que, por sua vez, está ligado a um conversor de freq³ência (2), onde as portadoras são transladadas para a faixa de freq³ências de radiotelefonia celular, como também tais portadoras passam por um filtro passa-faixa (3) de redução de harmónicos e de produtos indesejados fora da faixa, de modo que as portadoras filtradas possam ser introduzidas num módulo amplificador (4) cooperante para adequá-las à potência de transmissão desejada de acordo com a área predeterminada de bloqueio e inibição, sendo que, antes de serem irradiadas por uma antena (5), passa por outro filtro passa-faixa (6), com a mesma função do anterior (3) e, ainda, ditas portadoras irradiadas, combinando potência, freq³ência e modulação constituem um sinal de interferência na recepção dos aparelhos celulares que estão dentro da área predefinida de bloqueio e inibição.<B> CELLULAR RADIOTELPHONIA SIGNAL BLOCKER / TRANSMITTER <D>, comprising programmable modulators (M1), (M2) and (Mn) carrier generators (F1), (F2) and (Fn) of different frequencies and different modulations, each corresponding to a certain conventional cellular radiotelephony communication system, so that such frequencies and modulations can be introduced in an adder (1), where carriers of different frequencies are grouped on the same output cable which, in turn, , is connected to a frequency converter (2), where the carriers are transferred to the frequency range of cellular radiotelephony, as well as these carriers pass through a bandpass filter (3) to reduce harmonics and unwanted products outside the band, so that the filtered carriers can be inserted in an amplifier module (4) cooperating to adapt them to the desired transmission power according to the predetermined block area ure and inhibition, and, before being irradiated by an antenna (5), it passes through another bandpass filter (6), with the same function as the previous one (3) and, still, said irradiated carriers, combining power, frequency and modulation constitute an interference signal in the reception of cellular devices that are within the predefined area of blocking and inhibition.
