This document describes the design of a dual-loop 5.2GHz frequency synthesizer with an integer-N programmable divider in the low frequency loop. The synthesizer uses frequency multiplication, division, and mixing to generate a range of frequencies from 5.24GHz to 5.3GHz by changing the division ratio of the integer-N divider. The synthesizer is able to output 65mW to a 50立 load and has very low phase noise. It was designed under the advisement of Prof. Knepper.

This document discusses clock gating of linear feedback shift registers (LFSRs) to reduce power consumption. Traditionally, an LFSR uses feedback to generate pseudo-random bit sequences by shifting bits and XORing outputs. The document proposes adding clock gating circuits that only toggle flip-flops when new data is available. This results in around a 10% reduction in power usage for the LFSR, though additional transistors are needed for the clock gating circuits.Phase locked loop

A PLL or phase-locked loop is a control system that generates an output signal whose phase is related to the phase of an input signal. It consists of three basic elements: a phase detector that compares the phase of two signals and generates an error signal, a loop filter that filters the error signal, and a voltage-controlled oscillator whose frequency is controlled by the filtered error signal. PLLs are commonly used in applications such as frequency synthesis, signal demodulation, and motor speed control.Accoustic Junkies

Development of a receiver circuit for medium frequency shift keying signals.inventionjournals

Frequency shift keying (fsk) mode of digital signal information transfer switches between two predetermined frequencies of the carrier wave, either by modulating one sine wave oscillator or by switching between two oscillators.The need for a receiver to decode an fsk signal along the transmitting medium from a digital source code within about 5 kilometer radius for security monitoring of environment informed this work. The design of a receiver circuit at a frequency of 500 kHzfor an input frequency shift keying (fsk) signal from a transmitter is presented. The receiver is to receive an RF signal, amplify it, filter it to remove unwanted signals, and recover the desired base band information. It consists of an amplifier, tuned circuitsand mixers which filters the base-band information. A comparator circuit is incorporated, to detect the digital signal received. The output from the comparators is the digital equivalent of the coded signals sent by the transmitter circuit, and transferred to a microcontroller circuit, to act as a coded signal representing information from the transmitting end. The bode-plot response of the receiver to the incoming signals using a FET tuned circuit, shows that only frequencies above 470kHz, and below 495kHz are allowed to pass through the network with a resonant frequency of 483.553 kHz and a gain of 27.734dB, while others are totally attenuated. The reliability of the designed receiver circuit was evaluated for a 1 year continuous operating period and was found to be 74.7%.Area of application of this work include electronic policing of a defined environment with good success

This document discusses phase frequency detectors for phase locked loops (PLLs). It begins by analyzing existing phase frequency detectors and their circuit operations. It then proposes a new phase frequency detector with a simple structure that has no glitches and better phase characteristics. Simulation results show the proposed detector has higher operating frequency, lower phase jitter, and smaller complexity compared to prior designs. The document also covers types of phase detectors, including analog and digital, that are used in PLL systems. It describes the basic components of a PLL including the phase detector, charge pump, loop filter, and voltage controlled oscillator.CellExtender速 Antenna System Design Guidelines

The design of an Antenna system for a Cell Extender site needs to take into account the following specific factors:
a) The systems input and output frequencies can be relatively close.
b) The Cell (output) channels are fixed, but the Donor (RF Link) radios are frequency agile, as the channel can vary from call to call (to follow the Donor sites Traffic Channel allocation).
This Document is specially written to assist in Cell Extender antenna system design. As such, it is assumed that the reader has a good understanding of standard antenna system design techniques such as filter, multi coupler and other combiner technologies, as issues discussed in this Document only relate to specific Cell Extender application aspects. Matters such as elimination of Intermod products etc are not addressed in the context of this Document - please refer to normal common standard techniques and practices for these issues.
Please note that this Document provides design "Rules" only. Experience in antenna system design remains indispensable in actual practice! Wideband Complex Modulation Analysis Using a Real-Time Digital Demodulator

Demodulator circuit is a basic building block of wireless communication. Digital implementation of
demodulator is attracting more attention for the significant advantages of digital systems than analog systems.
The carrier signal extraction is the main problem in synchronous demodulation in design of demodulator based
on Software Defined Radio. When transmitter or receiver in motion, it is difficult for demodulator to generate
carrier signal same in frequency and phase as transmitter carrier signal due to Doppler shift and Doppler rate.
Here the digital implementation of Costas loop for QPSK demodulation in continuous mode is discussed with
carrier recovery using phase locked loop.EMI Unit II

A band pass filter allows signals between two specific frequencies to pass through, while blocking signals of other frequencies. To create a passive band pass filter, a low pass filter is connected in series with a high pass filter. This passes a selected range of frequencies while attenuating frequencies outside this range. In this project, the student designs a passive band pass filter with cutoff frequencies of 19 kHz and 39 kHz by using resistors R1 of 83 ohms and R2 of 500 ohms, along with capacitors C1 and C2 both of 0.01 microfarads. The student then tests the filter on different frequencies and charts the output voltages to analyze the filter's performance.Lecture intro to_wcdma

WCDMA uses spread spectrum technology to allow multiple users to access the same frequency band simultaneously. It spreads user data over a wide bandwidth through multiplication with unique spreading codes. At the receiver, the desired user's signal is recovered through correlation with the same spreading code. WCDMA employs RAKE receivers to combine signals from different propagation paths using maximal ratio combining for improved reception. Power control is used to manage interference between users communicating over the same frequency channel.Multiband Transceivers - [Chapter 6] Multi-mode and Multi-band Transceivers![Multiband Transceivers - [Chapter 6] Multi-mode and Multi-band Transceivers](https://cdn.slidesharecdn.com/ss_thumbnails/ch6-150613070935-lva1-app6891-thumbnail.jpg?width=560&fit=bounds)

This document describes a simple VHF receiver that can be built for around $20 using a superregenerative design. The receiver requires no special components or test equipment to construct. It uses a single JFET transistor as a superregenerative detector to provide high sensitivity of around 1 microvolt. The receiver can detect both AM and FM signals between 49-55 MHz with modifications allowing it to receive other VHF bands. With adjustments to the regeneration control and quench waveform control, the receiver can be tuned to receive narrowband FM transmissions with reasonable selectivity.Lesson5
