"WJ continues to rapidly expand its product lines and now offers its wireless infrastructure and wireless OEM customers a wide-variety of high-performance products," stated Javed Patel, senior vice president of sales and marketing at WJ Communications. "In addition to broadening our product line, we are offering aggressive pricing while still guaranteeing high quality and reliability. This compelling value proposition of WJ's products is becoming increasingly evident." New Semiconductor Products Dual-Branch Downconverters -- The performance characteristics of WJ's expanding CV line of integrated converters enable engineers to meet a wide range of design requirements for various infrastructure communication applications. These new devices meet the growing demands of new wireless systems in Europe and Asia. The CV211-2 and CV211-3 target the UMTS (Universal Mobile Telecommunications System) The GSM implementation of the 3G wireless phone system. Part of IMT-2000, UMTS provides service in the 2 GHz band and offers global roaming and personalized features. and W-CDMA See WCDMA. / IMT IMT, n.pr See inspiratory muscle training. 2000 bands. Each converter includes high-linearity amplification, frequency conversion, IF amplification and LO driver amplification in a 6 x 6 mm, 28-pin QFN package. Customized filtering can be enabled externally. These MCMs are realized with reliable and mature GaAs MESFET See FET. and InGaP HBT technologies.

Variable Gain Amplifiers -- Our recently released VG series variable gain amplifier line is the industry's first to integrate high performance amplifiers and attenuators within a single package. Superior thermal design allows the products to have a minimum MTTF See reliability. rating of over 100 years at a mounting temperature of +85(degree)C. The combination of high gain, low NF, and constant IP3 over a wide gain control range make these devices the best-in-class for base station transmitter and receiver chains that process complex digital modulation formats such as CDMA (Code Division Multiple Access) A method for transmitting simultaneous signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular phone technology from QUALCOMM that operates in the 800 MHz band and 1.9 GHz PCS band. , GSM, PCS and UMTS. The VG101 and VG111 are packaged in a 6 x 6 mm, 28-pin QFN.

2 Watt HFET - The FP31QF operates over the 50-4000 MHz frequency range. In cellular, PCS and UMTS applications, output power at 1dB compression is typically +34 dBm with a corresponding output third order intercept point of +48 dBm. Gain is 18 dB at 900 MHz. The FP31QF is packaged in a thermally-efficient, low-profile 6 x 6 mm QFN package and operates from a +9V drain bias with 450 mA of quiescent current. High Gain, High Linearity 0.5 Watt Amplifier -- The AH103 uses WJ's patented GaAs MESFET process technology and has an MTBF (Mean Time Between Failure) The average time a component works without failure. It is the number of failures divided by the hours under observation. MTBF - Mean Time Between Failures of greater than 100 years at a mounting temperature of 85 degrees C. The amplifier consists of two separate MMIC (Monolithic Microwave IC) An integrated circuit used in high-frequency applications such as mobile phones. Also known as "monolithic microwave/millimeter-wave IC," MMICs combine transistors and passive devices (resistors, capacitors, etc. amplifiers and allows for external inter-stage filtering or matching to best optimize performance for broadband or narrowband applications such as GSM, W-CDMA, CDMA, TDMA (Time Division Multiple Access) A satellite and cellular phone technology that interleaves multiple digital signals onto a single high-speed channel. For cellular, TDMA triples the capacity of the original analog method (FDMA). and UMTS infrastructure. The AH103 is tunable over the 70 - 2200 MHz frequency range and has the following performance: 29 dB gain, +27 dBm P1dB, +45 dBm output IP3. This performance along with excellent ACPR makes the AH103 an ideal driver amplifier for wireless and other applications where signal linearity is important.
