A Low-noise Band Pass Filter Using an X-band Injection- Locked Gunn Oscillator

In this paper, we report the design and implementation of a low-noise, tunable, active microwave band pass filter (BPF) which incorporates an injection-locked Gunn oscillator. The BPF has a centre frequency of 10.30 GHz and a 3-dB bandwidth of 52 MHz. Calculation shows that this active BPF can reduce the input signal AM noise by at least 38 dB. This BPF possesses signal amplification as well as...

A 910MHz Injection Locked BFSK Transceiver for Wireless Body Sensor Network Using Colpitts Oscillator

A 910MHz high efficiency RF transceiver for Wireless Body Area Network in medical application is presented in this paper. High energy efficiency transmitter and receiver architectures are proposed. In wireless body sensor network, the transmitter must have higher efficiency compared with the receiver because a large amount of data is sent from sensor node to receiver of the base station and sma...

A Novel Injection-Locked Oscillator MMIC with Combined Ultrawide-Band Active CombinedDivider and Amplifiers

A subharmonically injection-locked oscillator (ILO) MMIC for local oscillators, synthesizers, and phased-array antennas is proposed. An ultrawide-hand four-port active combineddivider in the oscillator feedback loop provides an FEToriented circuit topology extremely suitable for single-chip integration, and performs subharmonic injection locking at various subharmonic factors, l/n. Two types of...

Phase Noise in Externally Injection-Locked Oscillator Arrays

Previous investigations of noise in mutually synchronized coupled-oscillator systems are extended to include the effects of phase noise introduced by externally injected signals. The analysis is developed for arbitrarily coupled arrays and an arbitrary collection of coherent injected signals, and is illustrated with the specific case of linear chains of nearest neighbor coupled oscillators eith...
