Analog Devices Inc. (ADI), a leader in high-performance semiconductors for signal processing applications, introduces the ADF4350 synthesizer with on-chip (VCO (voltage-controlled oscillator) and PLL (phase-locked loop), which is the industry’s first fully integrated synthesizer to operate over an exceptionally wide continuous frequency range. Also, ADI introduces a family of...

Analog Devices Inc. , a leader in semiconductors for signal processing applications, introduced a pair of clock-generation and distribution ICs with the industry’s best combination of device integration, low noise, low jitter performance and signal output flexibility. The AD9520 and AD9522 multi-output clock generators include a 512-byte embedded EEPROM...

Modern wireless transmitters generally incorporate circuitry that directly or indirectly measures and regulates transmitted power. There are a number of reasons for this. Cellular standards such as WCDMA, CDMA2000 and GSM/EDGE demand that both base station and handset power be tightly controlled so that spectral leakage into adjacent channels...

A 0.1 to 2.5 GHz Logarithmic Amplifier for RF Detection Analog Devices Wilmington, MA Logarithmic amplifiers typically are used to measure widely varying signal levels at high frequencies. These signals may vary in amplitude by 90 to 100 dB at frequencies to 3500 MHz. In addition, some log amplifiers...
