Design of A 1.6GHz Low Phase Noise Oscillator

摘要：

In this paper,a method is proposed to improve the phase noise characteristic of a 1.6GHz oseillator(OSC),it uses two capacitors which have a difference of an order of magnitude as power filters to reduce its phase noise. Moreover this paper uses a positive feedback microstrip line and implement the common-emitter(CE) configuration of the transistor to improve the OSCs phase noise characteristic.The software ADS is used to simulate the OSC. Testing phase noise of the proposed OSC can reach -114.1dBc/Hz/1MHz.Testing output power of its fundamental is 9.18dBm.A satisfactory agreement is reached between simulating and testing results.
