Abstract: This application note illustrates the flexibility of the MAX7060 ASK/FSK transmitter. While the currently available evaluationkit (EV kit) has been optimized for the device's use in a specific frequency band (i.e., 288MHz to 390MHz), this document addresseshow the EV kit circuitry can be modified for improved operation at 433.92MHz, a frequency commonly used in Europe. Twoalternative match and filter configurations are presented: one for optimizing drain efficiency, the other for achieving higher transmitpower. Features and capabilities of earlier Maxim industrial, scientific, and medical radio-frequency (ISM-RF) transmitters areprovided, allowing comparison of the MAX7060 to its predecessors. Several design guidelines and cautions for using the MAX7060are discussed.

基于通用集成运算放大器,利用MASON公式设计了一个多功能二阶通用滤波器,能同时或分别实现低通、高通和带通滤波,也能设计成一个正交振荡器。电路的极点频率和品质因数能够独立、精确地调节。电路使用4个集成运放、2个电容和11个电阻,所有集成运放的反相端虚地。利用计算机仿真电路的通用滤波功能、极点频率和品质因数的独立控制和正交正弦振荡,从而证明该滤波器正确有效。 Abstract: A new multifunctional second-order filter based on OPs was presented by MASON formula. Functions, such as high-pass, band-pass, low-pass filtering, can be realized respectively and simultaneously, and can become a quadrature oscillator by modifying resistance ratio. Its pole angular frequency and quality factor can be tuned accurately and independently. The circuit presented contains four OPs, two capacitors, and eleven resistances, and inverting input of all OPs is virtual ground. Its general filtering, the independent control of pole frequency and quality factor and quadrature sinusoidal oscillation were simulated by computer, and the result shows that the presented circuit is valid and effective.

This m-file simulates MPSK (theoretical and simulated) with Gray coding This m-file simulates MPSK (BPSK,QPSK,8PSK)with theoretical and simulated results using Gray coding. Numerical examples of a satellite link design are shown using QPSK and/or 8PSK when the bit rate(Rb)is greater than the channel bandwidth Wc (band-limited channel).

In this paper, we provide an overview of the security concerns introduced by wireless LANs, current approaches to wireless LAN security, their limitations, and the weaknesses of various “band aid” security solutions. We conclude by describing how the ReefEdge Connect System provides a comprehensive solution to wireless LAN security.

This manual describes Freescale’s IEEE™ 802.15.4 Standard compliant MAC/PHY software. The Freescale 802.15.4 MAC/PHY software is designed for use with the Freescale MC1319x and MC1320x, family of short range, low power, 2.4 GHz Industrial, Scientific, and Medical (ISM) band transceivers, designed for use with the HCS08 Family of MCUs. The MAC/PHY software also works with the MC1321x family of short range, low power, 2.4 GHz ISM band transceivers that incorporate a low power 2.4 GHz radio frequency transceiver and an 8-bit microcontroller into a single LGA package. Throughout this manual, the term transceiver refers to either the MC1319x, MC1320x, or the internal counterpart inside the MC1321x System in a Package (SiP).
