May 07, 2014 // By Jean-Pierre Joosting
Triquint's TQL1600 is a highly integrated WLAN front-end module designed for 802.11a/n/ac applications. It contains a low noise amplifier (LNA) with bypass mode and a transmit/receive switch.

The architecture and interface are optimized for next generation WLAN integration into high throughput 802.11ac devices providing outstanding stable performance across temperature and voltage range.

With a frequency range of 5.15 to 5.875 GHz, the TQL1600 features a fully integrated, T/R SPDT switch and bypass LNA. It features 2.5 dB noise figure, integrated on-chip matching with 50 ohm I/O, integrated temperature compensated active bias, and CMOS compatible logic controls with integrated shutdown control pin. Gain is 13 dB in normal mode and -7 dB in bypass mode. The device operates off a +3 V to +5 V supply.

The TQL1600 is manufactured using TriQuint’s high reliability E/D pHEMT technology and is assembled in an ultra thin profile 16 pin 2.5 x 2.5 x 0.45 mm Pb-free, RoHS-compliant QFN package.
