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.
frequency dividers operate by subharmonic injection locking.

The SFDRO Series frequency phase locked oscillators
are designed to accommodate as many as six discrete frequency levels in one unit.
The PDRO series of 0.5 to 26.0 GHz phase locked oscillators
employ a unique technique to phase-lock microwave DROs to a 5 or 10 MHz crystal reference.
Bifurcation analysis is very useful for computing the locking range of analog frequency dividers and locked oscillators
, as shown below.
