TriQuint Base Station RFICs Integrate Unique Protections For Data-Intensive Mobile Device Networks

June 6, 2011

TriQuint Semiconductor 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. TriQuint is displaying these products at IMS 2011 in Booth 2218.

“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 minimize 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.”

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 linearization techniques commonly utilized to meet 3G/4G BTS system requirements. Unlike other linear driver amplifiers available today, TriQuint’s TQP7M9101 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 linear gain blocks that offer useful improvements. They appreciate that design requirements change all the time,” said Alexander Kopp, RF Designer, Andrew Wireless Systems / CommScope, Buchdorf, Germany. “A more linear RF signal is very important, and with very low current drain, we can reduce a system’s thermal dissipation. The TriQuint team has offered us great support.”

TriQuint’s two new amplifiers are ideal for 3G/4G wireless infrastructure applications including base transceiver stations, repeaters, boosters, tower-mounted amplifiers (TMA), remote radio heads, defense/ aerospace and other wireless systems requiring high linearity and gain with low power consumption.
