Product Description:
The TQL5000 is a low noise amplifier designed for 802.11a receive applications
for the WLAN market. The device exhibits industry-leading noise figure and
power consumption while maintaining high intercept performance. It requires a
Package Pin-out:
single 3 V supply voltage and draws 8 mA. The LNA is manufactured using
TriQuint’s GaAs pHEMT process and is packaged in an ultra-small, low-profile
1.3mm x 2mm x 0.4mm Lead Free SLIM-7 package.
