Coaxial Resonator Oscillators
Atlantic Microwave introduces coaxial resonator oscillators in the ACR series. The Series provides a stabilized fixed output frequency in the range 300 MHz to 3000 MHz with a minimum of +13 dBm of output power. Stability is achieved using a high Q ceramic resonator in a low noise silicon FET circuit with the output buffered to minimize frequency pulling. The frequency stability over the operating temperature range is better than ± 10 ppm per degree C. Harmonics are typically down at 30 dBc and spurious at better than 80 dBc. For a 600 MHz unit the typical phase noise is 95 dBc/Hz at 1 kHz offset, reducing to 140 dBc/Hz at 1 MHz offset. The DC input power is kept low with typically less than 100 milliamps being drawn from the standard +15 V supply for a +13 dBm output power unit. Power options include a range of DC voltages on the input and up to +20 dBm at the RF output.
