  1. 2008/07/21 TQM613027 - CDMA Cellular Band PA/Duplexer Module
Product Description
TriQuint’s TQM613027 is a fully matched CDMA cellular band PA/Duplexer (PAD) module for use in mobile phones.
The 7.0 x 4.0 x 1.2 mm, 20-pin module includes a SAW Duplexer, Power Amplifier, Differential input transmit filter, RF Power Coupler and Logic Controller.
With an RF Power Output up to 25.5dBm the TQM613027 PAD meets the strict ACPR and ALTR requirements for products designed to the CDMA IS-95/98/2000 standards.
It’s thin form factor and compact size, coupled with the low quiescent current, makes the TQM613027 ideal for today’s compact feature rich multi-media handsets requiring longer battery life.
TriQuint’s multilayer laminate technology provides low loss interconnect and optimized match between the duplexer, PA and filter enabling the TQM613027 to achieve only 40 mA of typical current consumption at maximum output power in low power mode (+13.5dBm).
The small 7.0 × 4.0 mm module replaces four separate components and matching requiring less board space.
TQM613027 provides handset designers with a simple to use surface mount module requiring minimal external circuitry for faster time to market and reduced BOM count.
