STVVGLNA - RF amplifier

Description

The STVVGLNA is a general-purpose, low-noise amplifier with a gain range of -17 dB to +15 dB.

Its gain is regulated either autonomously by an integrated AGC loop or by software control.

It can be used, for example, as an input amplifier for a satellite set-top box.

Features

  • 75-Ω single-ended input impedance.
  • 75-Ω single-ended or 150-Ω differential output impedance.
  • Dual differential or single-ended outputs.
  • Single 3.3-V DC supply.
  • Input frequency range 50 to 2150 MHz.
  • Fully integrated RF AGC with power monitoring.
  • Low external component count.
  • Low power consumption (145 mW typical).
  • Temperature range -35 °C to 85 °C.
  • Compatible with 5-V and 3.3-V I2C bus.
  • I2C bus control (option).
  • Four selectable I2C addr.
