Below are some of the new switches, filters, duplexers, dividers and other front end products being highlighted at IMS 2009 including some exciting new tunable technologies:
Trilithic Inc. released a small footprint diplexer for the DC to 2000 MHz band. Featuring low pass rejections of 60 dB minimum from 1200 to 2000 MHz and highpass rejections of 60 dB minimum from DC to 800 MHz. This compact mechanical package is rated at 10 W input power, features SMA connectors on all ports, high broadband isolation and wide frequency ranges. High power models are also available.
Reactel featured its growing line of ceramic filters at this year’s show. The company offers these units as both monoblock and resonator designs, and they are suitable for tape and reel packaging. They are also featured their extensive line of notch filters at this year’s show. The company offers these units in a variety of package sizes with power handling capabilities exceeding 1 kW.
M/A-COM Technology Solutions Inc., a provider of innovative microwave and RF design solutions, introduced a new family of surface mount broadband 2 to 20 GHz HMICTM PIN diode switches for Test Instrumentation, Satellite and other wide frequency range applications.
Aeroflex/Inmet introduced a new family of Wilkinson Power Dividers to complement its current offering of resistive divider models. The new units are two-way SMA models and are of octave and multi-octave designs covering the popular bands of 0.5 to 1, 0.8 to 2.5, 1 to 2 and 2 to 4 GHz. All models are currently available from stock.
By applying proven, patented UltraCMOS™ process and HaRP™ switch technologies, Peregrine Semiconductor developed DuNE™ technology, a new design methodology used to design digitally tunable capacitors (DTCs). Supporting a wide range of tuning applications—from tuning the center frequency of mobile-TV and cellular antennas to tunable impedance matching and filters—DuNE products offer power handling, performance, and size advantages that are unrivaled by any other commercially-available digital tuning technology.
Avago Technologies, a supplier of analog interface components for communications, industrial and consumer applications, announced the addition of an environmentally ‘green’ PCS FBAR Band Duplexer to its series of miniature duplexers. The ACMD-7409 duplexer, which was designed using Avago’s own FBAR technology, targets designers of PCS handsets, and data terminals operating in the US PCS frequency band.
The RLC Electronics’ Micro Miniature SMA Switch is a single pole two position type. The switch incorporates SMA connectors to allow high density packaging and excellent electrical performance through 26.5 GHz. The switch is available in failsafe and latching configurations with a choice of three different frequency ranges and three different coil voltages.
XMA Corp. announces the addition of its 20RP-6018-XXX 2 way Resistive Power Divider, which is rated for 2 W input power.
Teledyne Relays has introduced the SRF300/SRF303 series of ultraminature broadband TO-5 relays.
Pole/Zero introduced its Extended Range Filter, a digitally tunable, two-pole bandpass filter providing continuous coverage from 30 to 512 MHz. And achieving cosite interference protection in environments of multiple VHF/UHF tactical transceivers is now a reality through Pole/Zero’s introduction of the Mega-Pole high power (50 Watt) electronically tunable filter product line. When placed between the antenna and transceiver, the Mega-Pole yields excellent selectivity with minimal insertion loss, even in frequency hopping modes of operation.
JQL Electronics Inc. announced its new Thincore™ waveguide isolators and circulators.
SiGe Semiconductor expanded its Wi-Fi product range by introducing the SE2571U Front End Module that is specifically targeted at embedded applications including cellular handsets, gaming, digital cameras and personal media players (PMP). The SE2571U has been designed to address the specific challenges faced by OEMs needing to operate "direct to battery", and to improve performance, while addressing consumer led demand for coexistence with UMTS radios.
Sangshin Elecom, a supplier of ceramic filters, released its full line of broadband wireless and WiMAX filters. Features of Sangshin’s WiMAX/BBW product offering include: Frequency ranges of 2.0 to 6.0 GHz; Bandwidth: narrow band through ultra wide bands available; Configurations: 2.5 mm through 6 mm heights available and 2 through 6 pole designs; Footprint compatibility. Sangshin Elecom also presents a wideband 3.5 GHz monoblock filter for WiMAX applications. The MBP34RC3550S500A covers from 3300 to 3800 MHz and offers 35 dB rejection from 2300 to 2700 MHz. This filter offers 1.5 dB of IL in a small package size that measures 11 mm x 5.6 mm x 6 mm.
Murata Electronics North America, an innovator in electronics and the largest global supplier of ceramic passive components, introduced the world's smallest radio frequency (RF) switch connector. The new SWG series allows reliable RF circuit testing throughout the entire product life-cycle yet measures only 2.0mm x 2.0mm x 0.9mm. It also boasts an expanded frequency range currently not found in today's electronics industry. The enhanced connector saves space on the printed circuit board (PCB) making it ideal for numerous portable devices, high frequency measurement equipment and is well suited for WiFi, WiMAX, 4G, Bluetooth, ZigBee and UWB wireless standards.
