STW82101B
Part number
STW82101BTR
Description
The STMicroelectronics STW82101B is an
integrated down converter providing 8.5 dB of
gain, 9.5 dB NF, and a very high input linearity by
means of its passive mixer.
Embedding two wide band auto calibrating VCOs
and an integer-N synthesizer, the STW82101B is
suitable for both Rx and Tx requirements for
Cellular infrastructure equipment.
The integrated RF balun and internal matching
permit direct 50 ohm single-ended interface to RF
port. The IF output is suitable for driving 200-ohm
impedance filters.
By embedding a DAC with dual current output to
drive an external PIN diode attenuator, the
STW82101B replaces several costly discrete
components and offers a significant footprint
reduction.
The STW82101B device is designed with
STMicroelectronics advanced 0.35 µm
SiGe process. Its performance is specified over a
-40 °C to +85 °C temperature range.
