Maxim’s Secure RFID Keys Feature the 13.56MHz Interface Being Deployed for Access Control, e-Cash, and ID Cards Worldwide
Maxim Integrated Products introduces a new line of RFID keys and cards designed for the two-billion-units-per-year automatic identification, access control, and electronic cash (e-cash) markets. This new contactless RFID product family (the MAX66000/020/040/100/120/140) leverages the expertise utilized in the company's popular 1-Wire® secure authentication ICs, which protect intellectual property in embedded systems.
CRO3500C-LF Features Low Phase Noise
Z-Communications, Inc. announces a new RoHS compliant VCO (Voltage-Controlled Oscillator) model CRO3500C-LF in S-band. The CRO3500C-LF operates at 3500 MHz with a tuning voltage range of 0.5-4.5 Vdc. This VCO features a typical phase noise of -111 dBc/Hz @ 10 KHz offset and a typical tuning sensitivity of 5 MHz/V.
Development of Handheld Device RF Component Evaluation System
Murata Manufacturing Co., Ltd. has developed an evaluation system capable of evaluating all parts of an RF component, from transceiver IC to antenna switch. Support for evaluating characteristics of each part in a mobile phone transceiver circuit and characteristics of the transceiver component (RF component) , and support for IC matching in customer devices, will make circuit design easier.
New Miniature Zero-Bias Schottky Diode Detector
Res-net Microwave Inc. is introducing a miniature zero-bias Schottky diode detector to their current line of microwave and RF products. The Schottky diode is an order of magnitude faster than conventional PN diodes making them ideal for RF and microwave applications
Widest Bandwidth SMT Digital Attenuators Operate to 33 GHz
Hittite Microwave Corporation has introduced two new SMT packaged MMIC 5-Bit Digital Attenuators which are ideal for automotive, microwave radio, test equipment, military and space applications up to 33 GHz.
Two New High Linearity VGAs are Ideal for Microwave Radio
Hittite Microwave Corporation, announces the release of two new SMT packaged GaAs MMIC variable gain amplifiers (VGAs) which are ideal for VSAT, microwave radio, military, and test & measurement equipment applications from 5 to 27 GHz.
The diminutive successor to the large SMD quartz crystal is ready for release
As a result of their extremely low price, the very large and often cumbersome SMD quartz crystals in the HC-49/US-SMD metal housing series are frequently used in low-cost applications. Up until now, there was nothing from 10 MHz upwards with the capacity to replace the very low-priced, but very large SMD quartz crystals. Thus, there was nothing able to close the price gap between the crystals housed in metal and those housed in ceramic.
Freescale Sets New Benchmark with RF Power LDMOS Transistor for Broadcast Television Transmitters
Freescale Semiconductor has introduced an RF power LDMOS transistor that combines the industry's highest output power and efficiency with the greatest ruggedness of any competitive device in its class designed for UHF broadcast television applications.
Crystek Maximizes Performance And Efficiency In New 5800 Mhz Coaxial Resonator Oscillator (cro)
Crystek’s new CVCO55CXT-5800-5800 Coaxial Resonator Oscillator is a coaxial-based VCO with an internal proprietary frequency doubler. The CVCO55CXT family’s frequency doubling, 2X fundamental technology reaches new performance levels of lower phase noise and much lower harmonics over the competition, while achieving lower current consumption in the process.
Aspen Electronics has announced the immediate availability of a range of high quality, high power chip attenuators.
