... WIDEBAND LINEAR FM DETECTOR FOR SATELLITE TV The SL1454 is a wideband FM demodulator designed to operate with a carrier frequency between 70MHz and 150MHz. The internal circuitry of the device is similar to that of the SL1452 except that the quadrature demodulator operates at the input frequency. FEATURES Excellent Threshold Negligible Differential Gain and Phase Errors ...

... RF layout techniques and correct component selection will ensure optimum results. A good layout can usually be ensured by the simple precau- tion of keeping all components close to the SL1454, maintaining short lead lengths and ensuring a good low impedance ground plane. Double sided board layout enables these objectives to be easily met, but is not essential for satisfactory operation ...
