Philips Semiconductors
IF amplifier for satellite TV receivers
Product specification
TDA8011T
FEATURES
• High voltage gain, up to 860 MHz
• Low noise
• Large dynamic gain control
• High impedance differential input stage
• Low output impedance.
APPLICATIONS
• Second IF amplifier for satellite TV receivers.
DESCRIPTION
The TDA8011T is a broadband low-noise AGC amplifier
which is used for the second IF amplifier in satellite TV
receivers. The amplifier is powered from a single 5 V
supply. The amplifier gain can be easily controlled over a
large dynamic range by using a single ground reference
voltage. The two outputs are 180° out of phase and are
separately buffered. The two outputs can therefore, be
used in either the differential or asymmetrical mode.
