Dual-channel DVGA operates over broadband frequency range of 400 to 3600MHz
Mouser now stocks TriQuint's TQC9311, a dual-channel, digitally-controlled
variable gain amplifier (DVGA) operating over a broadband frequency range of
400 to 3600MHz.
The device features +36.5dBm OIP3 while providing digital variable gain with
31.5dB of gain range in 0.5dB steps through a 12-bit serial-mode control
interface. This combination of performance parameters makes the TQC9311
ideal for diversity or MIMO receiver applications requiring gain control
with high linearity and low noise figure such as wireless infrastructure,
LTE / WCDMA / CDMA / GSM, general-purpose wireless and diversity or MIMO
An evaluation board, the 0.4GHz to 3.6GHz TQC9311-PCB, is also available.
