Pasternack's 20 new phase locked oscillator models are offered with popularly fixed output frequencies of 50, 100, 500, 1000, 2000, 4000 and 6000 MHz.
This breakthrough has been achieved by a unique back-to-back layout structure of the injection locked oscillator. The analog-to-digital converter (ADC) on the BB LSI achieved the world's lowest power consumption of 12mW at a sampling rate of 2.3G samples/s as an ADC integrated in a 60GHz wireless chip by developing a simple comparator which does not increase the conversion noise.
The company's Frequency Locked Oscillator (FLO) represents a considerable improvement over the performance of conventional digitally tuned oscillators (DTO).
GoldenGate also provides support for RF pulsed designs; amplifier and oscillator startup/power-up analysis; VCO, free-running and locked oscillator, and frequency multiplier analysis; and active/passive mixer analysis; as well as support for diverse substrate technologies such as GaAs, Si-bipolar, Si-CMOS, Si-BiCMOS, SiGe, hybrid, PCB and multichip module technologies.
The verified theoretical model indicates that the minimum FM noise degradation of an nth order subharmonically locked oscillator is [n.sup.2]; and FM noise degradation can only be improved efficiently by increasing input power before it reaches the 3 dB point.
