Abstract :
A 16-channel surface-acoustic-wave grating-filter bank has been constructed on four y-cut LiNbO3 crystals. Each channel has a 4dB bandwidth of 6.7 MHz. The insertion loss at the peak of the passband of each channel is ¿32 dB, ±1.2 dB. The centre frequencies are 6.7 MHz apart and span the range 150¿250 MHz. This filter has been incorporated in a realtime spectral analyser.
