“…The spectrum at 145GHz of our PLL-BWO was obtained with another harmonic mixer and Tek2782, which is shown in Fig6, The phase noise of the phase locked BWO can be measured with another Tek2782 spectrum analyzer, according to the analysis, the phase noise can be estimated by using the phase-noise of the intermediate frequency and the local microwave frequency source which can be easily measured with the second spectrum analyzer, and the phase noise at several typical frequencies was shown in table 1. The measured SSB phase-noise of the phase-locked BWO is better than -63.3dBc/Hz at offset frequencies f m ,=1 kHz ~1 MHz, which are to some degree worse than the phase noise of the semiconductor devices [3], but the PLL BWO is desirable for dielectric measurement in the lab for its output power and broad frequency range. The commercial CP-PLL IC together with a Tek2782 spectrum analyzer's LO and a harmonic mixer can synthesize a BWO source.…”

“…Most importantly, a freerunning BWO is too noisy for precision measurements. Fortunately, phase-locked loop (PLL) commonly used for RF application [3,4,5], can translate the frequency accuracy of a high quality signal source to a tunable signal source and can translate the noise characteristics of a high quality signal source to a lower quality signal source. Recently, several charge-pump PLL(CP-PLL) and all-digital PLL have been reported [7] and widely used for low cost IC solutions.…”

“…The PLL analysis, simulation and practical results will show that the commercial IC ADF 4007 has a fast, accurate response for locking the BWO to the Tek2782 spectrum analyzer, its IF frequency is at 3.525GHz. According to the analysis, the phase noise of the phase locked BWO can be estimated using the phasenoise of the intermediate frequency and local microwave frequency source [3].…”

The processing of analysis, design and phase noise measurement of the Backward-wave oscillator(BWO) based on a 3rd order PLL is presented in this paper. The design utilizes a Charge-pump Phase-locked loop IC and a harmonic mixer in conjunction with a spectrum analyzer locking the BWO to a Tek2782 spectrum analyzer. We adopt a GPIB cable connecting the spectrum analyzer to a computer and created a virtual instrument by Labview program on the screen. The SSB phase-noise of this Phase locked BWO was measured and the typical value in the frequency range 135GHz to 160GHz is better than 63dBc/Hz at offset frequencie 1 kHz.

“…Low‐phase noise radio frequency (RF) signals have many applications in RADAR, electronic warfare and high speed communication systems. There are several different methods to generate low‐phase noise RF signals at high frequencies (>5 GHz); some of these methods are frequency stabilized mode‐locked lasers, opto‐electronic oscillators, sapphire loaded cavity‐based oscillators, and phase‐locked loop‐based oscillators . Each method has its own advantages and disadvantages; one can choose any of these methods depending on the application and need (size, power consumption, working environment, etc.).…”

In this article, we are presenting the experimental results and theoretical analysis of radio frequency (RF) phase noise filtering properties of a high Q cavity actively driven mode‐locked laser. The experimental results show that, the phase noise of a 10 GHz RF tone can be filtered by at least 10 dB at 200 kHz offset frequency. A theoretical analysis on the limits of phase noise filtering due to the spontaneous emission and the frequency mismatch between the laser cavity modes and the synthesizer frequency is also included.

“…A clock generator in general provides analog, digital, or mixed‐signal systems with a system clock [1]. For precision clock generation, a phase‐locked loop (PLL) is ordinarily used [2–4]. The PLL includes an off‐chip temperature compensated crystal oscillator (TCXO) or even an oven‐controlled crystal oscillator (OCXO) to supply a stable and accurate frequency reference [4].…”

frequencies which are 200, 500, 800, and 1000 MHz. The patterns are called divisive as they are consists of main lobes as shown in Figure 7. The energy distributed is not equal which is right lobe is smaller in magnitude compared to the left lobes because some energy released has been absorbed by the resistor. CONCLUSIONBased on Refs. 3, 5, 8, and 9, the physical dimensions of the planar monopole antenna presented are considered small in size and broadband. This antenna is fed from the bottom of the patch. After a lot of parameter optimization routine, the compact size with optimum performance is obtained. By integrating 50 dual bevel angle with a single 100 X resistor, the more current flow to the ground and the radiating element has become more magnetic. Thus, the proposed antenna achieved a very wideband impedance bandwidth of approximately more than 200%. A prototype antenna was designed, fabricate and the performance measure is presented. The antenna has the ability to operate for the VHF and partial of UHF spectrum. Besides the targeted white spaces (broadcasting spectrum) is also catered by this antenna. This gives it more credit as a great choice for the CR applications in the future.ABSTRACT: This article presents a simple complementary metaloxide-semiconductor (CMOS) ring oscillator using a voltage-controlled delay and RS-latch, including a compensation circuit for the process and temperature variations. The compensation circuit, added to the original bias circuit, is a simple current sinker which is referenced through a current mirror circuit. The proposed oscillator was designed and implemented using a 0.13 lm CMOS process. The oscillator exhibited a significantly improved frequency variation of 64.25% for a wide temperature range of from À40 to 80 C. Without the compensation circuit, the variation would have been 613.39% from the center frequency of 2.33 MHz. The oscillator also showed a low sensitivity of 0.084% to process variation, according to a Monte-Carlo simulation with 1000 iterations.
