Fundamental-mode Pierce oscillators in the 250-300-MHz range have been realized utilizing a unique form of a bulk-acoustic-wave (BAW) resonator. Phase noise greater than —100 dBc/Hz (1-kHz offset) has been extrapolated from data collected on oscillators operating at — 22 and —24 dBm. Higher power levels to +6 dBm have been achieved. A linear-model design was used. The circuit topology used and resonator fabrication technique shows great promise for the creation of MMIC circuits in the 200-MHz-2-GHz range.
