Description
The TriQuint TGA8161-SCC is a monolithic 3-stage general purpose 500 MHz to 3
GHz amplifier designed as a complementary product to the TGA8061-SCC, 0.1 to 3.5
GHz amplifier.
The TGA8161-SCC is a self-biased amplifier with gain control capability, reduced
power consumption, and 3 dB bandwidth performance over the 100 MHz to 4 GHz
band. Typical output power at 1 dB gain compression is 12 dBm. The TGA8161-SCC
is ideal for receiver applications and may be used in gain control or switching
applications.
The TGA8161-SCC is supplied in chip form, with backside metallization, for ease of
assembly.
