New Semiconductor Products

10V Power Amplifier Module - WJ recently launched the 1.9 GHz PAS/PHS high performance amplifier module offering excellent linearity and reliability. The ECM168 is a three-stage 1.9 GHz amplifier designed for general-purpose repeater and base station applications. This device utilizes InGaP HBT process technology. Key features include; 33.5dBm output power, a single 10V supply, 33dB typical gain and excellent ACPR2 @ 600kHz offset. No negative voltage is required and the efficiency is in excess of 20%. The ECM168 is housed in a low cost, flange mount package measuring only 29 x 13 x 4 mm.

High Dynamic Range CATV Amplifier - The AH22S is a high dynamic range amplifier targeting the CATV market. The AH22S includes two matched devices and is ideal for operation in a push-pull configuration to achieve low distortion characteristics at 39 dBmV/channel (77 channels). The push-pull amplifier is capable of achieving high performance levels of -74 dBc CSO and -80 dBc CTB above 100 MHz. The dual amplifier is housed in an industry standard surface-mount SOIC-8 package with all devices being 100% RF and dc tested. This device offers low VSWR, good gain flatness and high gain over the entire CATV frequency band depending on customers' applications.

High Dynamic Range PCS-Band MMIC Mixer - The MH1A is a passive FET mixer that provides high dynamic range performance in a low-cost SOIC-8 package. The GaAs MESFET based MH1A uses patented techniques to realize +35 dBm Input IP3 at an LO drive level of +17 dBm. This device operates over the 1700-2000 MHz RF frequency range featuring a low noise figure of 8.5 dB and low conversion loss of 8.8 dB. Typical applications include frequency up/down conversion, modulation and demodulation for receivers and transmitters used in 2.5G and 3G PCS, DCS1800, and PHS systems.

New RFID Products

WJ's RFID product portfolio includes the new multi-protocol MPR 5000 and MPR 6000 PCMCIA Type II Cards, OEM Modules and ASICs for RFID applications worldwide. These multi-protocol cards can read EPC Class 0 and EPC Class 1 tags and program/write EPC Class 1 tags. The MPR series is ideal for OEMs looking for a convenient platform for software/system development of host APIs for RFID reader products. These cards are also ideal for printer, handheld, fixed, applicator and other integrated RFID systems where performance and cost are critical.
