M. Hikita et al., A WIDE-BAND SAW RESONATOR AND ITS APPLICATION TO A VCO FOR MOBILE RADIO TRANSCEIVERS, IEEE transactions on vehicular technology, 43(4), 1994, pp. 863-869
A new wideband SAW resonator has been developed for SAW-VCO's used in
mobile radio communication transceivers. The resonator is based on a r
epeated structure of pairs of electrically connected IDT's, which prov
ides a high Qu and a wide frequency bandwidth. An experimental SAW-VCO
module measuring 8 x 8 mm(2) offers a frequency-variation bandwidth o
f about 20 MHz, a C/N of 75 dB, and an output power of 3-4 dBm at 900
MHz, satisfying the specifications for Japanese MCA and business-use r
adio transceivers.
