Fully Matched Cascadable Amp
The TQP3M9009 has been added to the company’s low noise gain block family for high performance 3G/4G infrastructure. This cascadable amplifier is fully matched internally, allowing designers to focus on system level needs. It operates over a broad .05 to 4 GHz frequency range.

Bandpass Filter
Part number 2965-SMA is a 500 MHz bandpass filter. The filter has a typical 1 dB bandwidth of 8 MHz, insertion loss of 6.5 dB and typical 40 dB bandwidth of 52 MHz. It is supplied in a 0.6 x 0.6 x 2.25" SMA package and may be customized for other center frequencies and bandwidths.

UltraFast™ Digitally Programmable LDO
The LT3071 is the second in a family of digitally programmable linear regulators with the lowest dropout voltage, lowest noise, and fastest transient response of any monolithic 5A LDO currently available. Dropout voltage at 5A is an ultralow 85mV. Its QFN package is 4 x 5 x 0.75mm in size.

Microwave Power MMIC
A 4W C-Band GaAs MMIC for satellite applications, the TMD0608-4 operates in the 5.65 to 8.50 GHz range. With this broad bandwidth, a high gain of 27 dB throughout the operating range, and 50 ohm internal matching, this device is well suited for use as a pre-amplifier in C-Band satellite and terrestrial communications.

USB Power Sensors
The U2000 Series USB-based power sensors are compact, portable solutions that allow average power measurements without power meters. All sensors, except the U2004A model, feature internal triggering and trace display capabilities. Current users of these sensors can upgrade their firmware for free.

Directional Couplers
Miniature air dielectric directional couplers are rugged, lightweight devices that offer lower insertion loss than comparable stripline units. The simplified construction allows for greater flexibility in creating customized configurations. Any port can be used as the input with these devices.

Elliptic Lowpass Filter
Part number 2969-SMA is a high order 10 MHz elliptic lowpass filter with sharp transition to the stopband and high stopband attenuation. Typical 1 dB bandwidth is 10.9 MHz with minimum 84 dB attenuation at 13.125 MHz. It is supplied in a 0.6 x 0.6 2.25" package with SMA connectors.

Directional Coupler
Model 110067016 directional coupler has a frequency range of 10 to 67 GHz, 7.25 directivity, and maximum VSWR (any port) of 2.0. Coupling (with respect to output) is 16 +/-1.1 dB and frequency sensitivity is +/-2.0 dB. Operating temperature range is -54 to +85ºC.

Fixed Frequency Synthesizer
The SFS6400A-LF in C-band is a single frequency synthesizer that operates at 6400 MHz. This synthesizer features a typical phase noise of -88 dBc/Hz @ 10 KHz offset and typical sideband spurs of -65 dBc. Its PLL-V12N package measures only 0.60 x 0.60 x 0.13".

Higher Power GaAs FETs
The company has expanded its Ku-Band GaAs FET lineup with two higher output power devices rated for 18 and 30W. Models TIM1213-18L and TIM1213-30L operate in the 12.7 to 13.2 GHz range and are targeted for use in microwave radios for microwave links and satellite communications.

EMT SMT Diode TVS Connectors
Now available are transient protection solutions embedded within the connector shell utilizing surface mount (SMT) diodes. Using SMT diode technology allows for increased flexibility in the packaging of transient protection within the connector, saving both space and weight.

Low Noise Gain Block
Model TQP3M9008 is a new low noise gain block that offers high gain over a broad .05 to 4 GHz frequency range. It is a cascadable amplifier that requires no external matching components and can reduce BOMs. The gain block provides 35.5 dBm OIP3, while maintaining a low 1.3 dB noise figure.

Morelli Joins IW
Industry veteran John Morelli was appointed vice president/New Business Development of IW’s Microwave Product Division in Danbury, CT. He became president of the division on April 1. Morelli has more than 40 years of experience in development, design, manufacturing and marketing of microwave connectors, components and cable assemblies. Most recently, he was with SV Microwave in a senior management position. Prior to that, he worked with industry leaders M/A-COM, AMP and Kings Electronics, working in various positions from design up to senior management. He is credited with the development of the BMZ and ZMA families of connectors and components and was part of the industry team that developed the 2.4 and 1.85mm families of products. Morelli has been an active participant in the EIA connector standards group in support of DSCC and is a Deputy Technical Adviser for the U.S. National Committee in support of IEC standards. He participated in the IEEE 287 precision standards group. IW’s Microwave Product Division specializes in the design and manufacture of high performance cable assemblies, wire and cable for military and commercial applications

Ole RF/Microwave Peddlers Gathering
The Southern California Chapter of the ad-hoc Ole RF/Microwave Peddlers held their annual gathering last month. The venerated group, organized and led by Chuck Swift, C.W. Swift & Associates, enjoyed a docent-led tour and ceremony at the Reagan Presidential Museum in Simi Valley. Following the tour, the group met at the home of Phillip Cox (formerly of M/A-COM, Signal Technology and California Amplifier) for a southwestern dinner and open discussion on the evolution of the aerospace industry over the past 35 years.

Mouser, Linx Team Up
Mouser Electronics, known for its rapid introduction of the newest products, has reached a global distribution agreement with Linx Technologies, a leading provider of versatile RF products. Each will add the other’s products to their own distribution roster, making both strategically positioned to address the needs of the exploding RF marketplace.
