QPB0066

    5 - 500 MHz Digital Controlled Variable Gain Amplifier

    Key Features

    • 5 MHz to 500 MHz Operation
    • Dual 6-Bit Digital Step Attenuator
    • SPI Serial Control Programming
    • Max Gain = 44 dB at 100 MHz
    • Gain Control Range = 63 dB (0.5 dB Steps)
    • High OIP3 / P1dB = +38 dBm / 22.6 dBm
    • +5 V Supply for DSA and +8 V Supply for Amplifier with a Drop Resistor
    • Small 28-Pin, 6.0 mm x 6.0 mm MCM
    • Power-up Programming

    The QPB0066 is a digital controlled variable gain amplifier featuring high linearity over the entire gain control range with noise figure less of 4.3 dB in its maximum gain state. The gain is controlled by the dual 6-bit digital step attenuators programmed with a 12-bit Serial Peripheral Interface (SPI). The module is easy to use with a few external DC blocks and RF chokes.
