partners, as well as other semiconductor companies – in large part due to the economies of scale we’re able to bring to the equation. As we release new products based on GaN, we’ll also be working with our partners to build a European supply chain that optimizes costs at every step in the value chain, and continue to offer our customers choice when it comes to selecting the best alternatives – LDMOS or GaN – for high-efficiency applications,” commented John Croteau, senior vice president and general manager, high performance RF, NXP Semiconductors.


Engineering samples of NXP’s first GaN PAs are available immediately and are expected to be available for volume production at the end of 2011.


TriQuint introduces base station RFICs with unique integrated protections


The firm’s experts will be showing new ways to lower power consumption and prevent network system ESD, RF over-drive & DC over-voltage failures at IMS 2011.


TriQuint Semiconductor, an RF solutions supplier and technology innovator, has released the first members in a new family of integrated RF products that lower power consumption while protecting mobile networks from disruption and service failures.


TriQuint’s newest base transceiver station (BTS) network devices join 12 other new power and filter infrastructure solutions introduced in the first half of 2011.


“We listened to our customers in developing these products,” said Vice President Brian P. Balut. “Consumer demand for smartphones and tablets means more bandwidth through the network. That leads to the requirement for greater linearity in the RF chain. At the same time, our customers want to minimise power consumption, and they want devices that withstand spikes and other stresses that may occur in the field. These two new products uniquely address all these needs.”


TriQuint is focused on bringing performance 118 www.compoundsemiconductor.net October 2011


innovation to essential building blocks in the global network. This network is fraught with demand, and it’s not going to let up; by 2015, the amount of mobile data traffic contributed by tablets alone is expected to equal that of mobile data traffic from all devices combined in 2010.*


TriQuint new base station RFICs deliver high performance that helps ensure more ‘fault-free’ 3G/4G network operation.


TriQuint’s new base station devices, starting with the 0.25 W TQP7M9101, provides high gain and linearity with very low current consumption—just 88 mA in a typical 5 V design. The 0.5 W TQP7M9102 is also now available; it provides highly-linear performance, low current consumption and greater gain.


Setting these amplifiers apart from others now available is TriQuint’s patent-pending integrated protection features that include means to guard against ESD and DC over-voltage electrical spikes.


TriQuint also integrates RF over-drive protection that reduces the chance of damage from high signal levels often seen in systems employing digital pre- distortion linearisation techniques commonly utilised to meet 3G/4G BTS system requirements.


The firm says that unlike other linear driver amplifiers available today, its TQP7M9101 module also integrates matching circuits that eliminate the need externally. These integration benefits reduce the overall BOM and provide easier-to-use solutions that are especially important when fast time-to- market is a key manufacturer strategy.


“TriQuint regularly releases new amplifier and
