General Description
The TQP369185 is a general-purpose buffer amplifier
that offers high dynamic range in a low-cost surface-
mount package. At 1.9 GHz, the amplifier typically
provides 19 dB gain, +31.7 dBm OIP3, and 4.6 dB Noise
Figure while drawing 75 mA current. The device
combines dependable performance with consistent quality
to maintain MTTF values exceeding 100 years at
mounting temperatures of +85°C. The device is housed
in a lead-free/green/RoHS-compliant industry-standard
SOT-89 package.
The TQP369185 consists of a Darlington-pair amplifier
using TriQuint’s high reliability InGaP/GaAs HBT
process technology.
Internal active bias enables
operation with only DC-blocking capacitors and an RF
choke on the DC bias feed. This broadband MMIC
amplifier can be directly applied to various current and
next generation wireless technologies such as CDMA, W-
CDMA, and LTE. In addition, the TQP369185 will work
for other various applications within the DC to 6 GHz
frequency range.
