MMIC Trio Launch Key New Products at Show

In the past week RFMD, TriQuint and Anadigics have made significant news announcements timed for the European Microwave Week (EuMW) in Manchester, UK. RFMD has begun shipping the RF3158 high-power, dual-mode EDGE amplifier module to LG Electronics, Anadigics Inc of Warren, NJ, USA is shipping its HELP2 EV-DO PA MMICs to Samsung Electronics and TriQuint Semiconductor introduced a pair of high output third order intercept GaAs amplifiers.

RFMD is shipping its RF3158 high-power, dual-mode EDGE amplifier module to LG Electronics. Leveraging its highly-integrated linear transmit architecture, the RF3158 integrates into multiple reference design platforms for EDGE-enabled mobile devices.
The RF3158 is designed to support EDGE radios that use a linear or small-signal polar modulation transmit architecture. Designed to be the final amplification stage in a dual-mode GSM/GPRS/EDGE mobile transmit lineup, its gain and linearity line-ups enable handset makers to optimize the transmit chain to meet varying implementations of linearity, efficiency and output power, says RFMD. Fully quad-band capable, the module operates in the 824-915MHz and 1710-1910MHz bands.

RFMD anticipates continued sales growth in the EDGE market, which it forecasts will grow approximately 100% in 2006.

Anadigics says it is shipping the HELP2 EV-DO power amplifier products to Samsung Electronics for its new SCH-a870 CDMA handset, which is being offered by the top CDMA wireless service provider in the US and features a colour display, camera with flash, Bluetooth, and speakerphone.

The SCH-a870 uses the AWT6307 and AWT6308 HELP2 PAs for US cellular band and PCS band operation, respectively. The highly integrated 3x3-mm HELP2 PAs eliminate the need for external voltage regulation, reducing BoM and maintain pin-to-pin compatibility with existing 4x4-mm amplifiers, reducing PCB space requirements by up to 50%. The Anadigics 'second-generation high-efficiency-at-low-power' (HELP2) EV-DO PAs are said to provide exceptional efficiency, reducing average current consumption by 50% as well as reducing power consumption and increasing talk-time.

Finally, TriQuint Semiconductor is to introduce two new high-OTOI GaAs amplifiers TGA4530 and TGA4530-SM are designed for point-to-point radio, K-band satcoms and point-to-multipoint network infrastructure applications.

Dan Green, TriQuint Broadband Products marketing director, said: "By working closely with our customers we have been able to significantly improve the performance and lower the cost of mm-wave amplifiers by investments in device modelling, design and testing to support the demand for high power mm-wave MMIC and packaged devices. The TGA4530 will be offered in both a surface mount package and as a die product to provide the flexibility in delivery format that our customers require."

The TGA4530 offers a frequency coverage of 17-21 GHz, and provides 42dBm OTOI, 30dBm output power at the 1dB compression point at a bias of 7 V (825 mA, Idq); typical gain is 20dB with input and output return losses of 15dB. It also incorporates an on-chip power detector, thus reducing BoM by eliminating the need for a discrete power detection circuit. The TGA4530 is the MMIC version; the TGA4530-SM is packaged.
