- The Casio FM Card RD-10, Japan, has the size of a credit card and a thickness of about 2 credit cards only. It is called "the thinnest Radio in the World" and we believe that this is correct. There are also other models of this type of FM-radio with separate ear phone. The FM Card Radio RD-10 uses a lithium battery CR2016 of 3 volt and weighs including battery 21 grams - more or less the same as the thicker Citizen FM Card Radio. The RD10 (RD-10) receives from 88 to 108 MHz. The RD-10 comes with the IC Philips TDA7020T which has a FLL (Frequency Locked Loop) system with an intermediate frequency of 76 kc. The selectivity is obtained by active RC filters. The TDA7020T includes RF input stage, mixer, local oscillator, IF amplifier/limiter, frequency detector, mute circuit, loop amplifier, internal reference cirquit, LF amplifier for mono earphone amplifier (or MPX filter) and a field-strength dependent channel separation control facility. Thickness measured : 2,2mm
