Microwave Engineering Europe - December 2007 - (Page 38) 38 PRODUCTS 2778 to 2945 MHz VCO delivers high linearity Crystek’s CVCO55CC-27782945 VCO operates from 2778 MHz to 2945 MHz with a control voltage range of 0.1 V to 16 V. This VCO features a typical phase noise of -110 dBc/Hz at 10KHz offset and has excellent linearity. The VCO is packaged in the industry standard 0.5- x 0.5-inch (1.27- x 1.27-mm) SMD package. Input voltage is 8.0 V, with a maximum current consumption of 40 mA. Pulling and Pushing are minimized to 5.00 MHz and 2.00 MHz/V, respectively. Second harmonic High gain WiMAX antenna 65-degree half power beam width and 17 dBi gain Laird Technologies has introduced a 2.5 GHz 65degree dual slant 45 WiMax base station antenna. The company designed the antenna to be fully compliant with the ETSI EN 301.525 CS pattern specifications resulting in consistent and reliable antenna performance. This in turn helps the operator create a troublefree wireless network, and ultimately results in improved customer satisfaction. The antenna operates across the 2.3 to 2.7 GHz frequency band. It also features a 65degree half power beam width and 17 dBi gain in a compact package. The maximum null fill (-25 degree) feature ensures consistent signal level throughout the wireless coverage area. Well controlled upper sidelobes reduce interference and the antenna includes a stable tilt bracket system that accommodates up to four-inch diameter mounting poles. www.mwee.com/204201572 suppression is -15 dBc typical Typical applications include digital radio equipment, fixed wireless access, satellite communications systems, and base stations. www.mwee.com/204201595 High stability microwave frequency counter cuts cost-of-ownership by up to 30 percent for extra options while supporting high-accuracy measurements of burst signal carrier frequency, pulse width, and CW signal carrier frequency. The built-in higherstability oscillator helps cut the cost of ownership by up to 30 percent compared to the previous F2400B series. A new vacuum fluorescent display has been added to the analog meter and Go/No Go evaluation functions of the previous MF2400B series, offering a clearer and wider-angle view of settings and results in every test environment for higher operation efficiency. The series offers three models, the MF2412C supporting 20 GHz, MF2413C supporting 27 GHz, and MF2414C supporting 40 GHz, meaning customers benefit from tailored solutions meeting individual measurement requirements. www.mwee.com/204201739 40 W GaAs MMIC T/R switch cellular and mobile applications over 0.1 to 2.1 GHz Hittite Microwave has released a 40 W GaAs MMIC positive control T/R switch for Cellular/3G, TD-SCDMA, Private Mobile Radio and Automotive Telematics applications from 0.1 to 2.1 GHz. The HMC646LP2E is a low loss, high linearity GaAs MMIC 40 W switch that provides exceptionally high P0.1 dB compression of +46 dBm (at 10 percent duty cycle) as well as an Input IP3 of +74 dBm on the Transmit (Tx) port, making it ideal for use in transmit-receive or LNA protection applications. Its superior low distortion at high input power levels as well as its fast switching characteristics makes it an ideal choice Anritsu has launched the MF2400C Microwave Frequency Counter, succeeding the popular MF2400B line. The MF2400C series is a general-purpose instrument designed for measuring the burst signal, carrier frequency and pulse width required for the evaluation of a wide range of radio equipment, such as mobile terminals, base stations, radar, microwave repeaters and related devices. The previous MF2400B series offered an optional high-stability crystal oscillator for higher-accuracy measurement; however the MF2400C incorporates the same higher-stability oscillator with an order-of-magnitude better aging rate as standard, thus eliminating the need for the demands of modern basestation infrastructure. On-chip circuitry enables the HMC646LP2E to operate with single positive control voltages from 0/+3 V to 0/+8 V, with very low DC current consumption. The HMC646LP2E is conveniently housed in a small RoHS compliant 2x2 mm DFN surface mount package. http://www.mwee.com/204201730 Self-biased amplifier achieves +15 dBm P1dB and 15 dB gain Mimix Broadband offers the CMM9000-QT two-stage feedback driver amplifier in a 3x3 mm surface mount QFN package. Using 0.50 micron gate length GaAs MESFET device model technology, the buffer amplifier covers the 1.5 to 6 GHz frequency bands and achieves a small signal gain of 15 dB, with +15 dBm P1dB across the band. The device includes integrated DC blocking capacitors and RF choke inductors on-chip and is fully matched. www.mwee.com/204201823 Microwave Engineering Europe ● December 2007 ● www.mwee.com 038_MWEE.indd 38 23/11/07 14:10:21 http://www.mwee.com/204201572 http://www.mwee.com/204201595 http://www.mwee.com/204201730 http://www.mwee.com/204201823 http://www.mwee.com/204201739 http://www.mwee.com
