High-Q oscillators up to 200 MHz are built using bulk quartz crystal resonators. For UHF and microwave frequencies, transmission line and cavity oscillators offer higher Q than L-C designs, but they are larger. SAW resonators fill the need for small highloaded-Q oscillators in the frequency range 200 to 1,200 MHz. Typical unloaded Qs are 6,000 to 12,000.
